Substrate v2: Generic parent-child CRUD app (Phases 2A-1, 2A-2, 2A-3) (#33)

* Phase 2A-1: Update ItemTag schema to Rails API v2 (#29)

Free-Android port of [nativeapptemplate/NativeAppTemplate-Android#38](nativeapptemplate/NativeAppTemplate-Android#38).

Updates the ItemTag schema to match the Rails API v2:
- rename queue_number -> name
- add description, position
- remove scan_state, customer_read_at, already_completed, display_shop_server_path

Data layer only — Scan/NFC code is kept and adapted to compile against
the new schema. Full Scan/NFC deletion is Phase 2A-2, UI rewrite is
2A-3, further test work is 2A-4.

Key changes
- item_tag_data.proto: queue_number -> name; reserve 5/7/11; add
  description and position.
- Model (Attributes/Data/ItemTag/Shop/ItemTagData/ItemTagBodyDetail):
  field renames; added getName/getDescription/getPosition; dropped
  getScanState/getCustomerReadAt/getAlreadyCompleted/getDisplayShopServerPath.
- Meta.maximumQueueNumberLength default 0 -> 256 so the meta field is
  optional (matches iOS).
- ItemTagCreateViewModel / ItemTagEditViewModel: queueNumber -> name;
  hasInvalidDataQueueNumber -> hasInvalidDataName; updateQueueNumber ->
  updateName.
- Removed production call sites of deleted fields in
  ShowTagInfoScanResultView, ScanViewModel, ShopDetailCardView,
  ShopDetailView — each flagged with a // TODO: removed in Phase 2A-2
  marker.
- Deleted NumberTagsWebpageListView(Model) entirely and removed the
  navigation wiring / ShopSettings entry.
- Updated test fixtures (item_tag.json, item_tags.json) and affected
  unit tests. ScanViewModelTest deleted ahead of 2A-2.
  NumberTagsWebpageListViewModelTest removed.

Verified locally: ./gradlew assembleDebug, test, spotlessCheck all
BUILD SUCCESSFUL.

* Phase 2A-2: Remove NFC / QR / Scan (#31)

Mirrors NativeAppTemplate-Android PR #39 (which itself mirrors iOS PR #50).
After this, the app is a generic CRUD shell with Shops and Settings tabs;
ItemTagDetailView is a placeholder (name, description, state, completedAt).

### Deletions
- NfcError; ItemTagWriteView/VM + test
- ui/scan/* (ScanView, ScanViewModel, DoScanView, DoScanViewModel,
  CompleteScanResultView, ShowTagInfoScanResultView, ScanNavigation)
  + DoScanViewModelTest
- Models: CompleteScanResult, CompleteScanResultType, ShowTagInfoScanResult,
  ShowTagInfoScanResultType, ItemTagInfoFromNdefMessage, ItemTagType,
  ScanState, ItemTagData
- Proto schemas: scan_result.proto, item_tag_data.proto,
  item_tag_info_from_ndef_message.proto
- res/raw/nfc_reader.json

### Strip / rewrite
- MainActivity: dropped NFC imports, onNewIntent, ACTION_NDEF_DISCOVERED
  handling, singleTask launch mode
- MainActivityViewModel: rewritten minimal (logout + permissions refresh +
  didShowTapShopBelowTip)
- NatAppState / NatNavHost / TopLevelDestination: dropped SCAN_TAB,
  shouldNavigateToScanView flow, navigateToScan helper, scan nav graph
- ShopDetailView / VM: dropped queue instructions block, ReadInstructionsTip,
  didShowReadInstructionsTip; renamed resetItemTag -> idleItemTag and swipe
  action "Reset" -> "Idle" (width 64dp -> 96dp)
- ShopSettingsView / VM: removed the "Reset Number Tags" section, resetShop
  flow
- ItemTagDetailView / VM: placeholder (name, description, state, completedAt)
- LoginRepository (+ Impl) / NatPreferencesDataSource: dropped scan-related
  setters/getters, didShowReadInstructionsTip
- ShopRepository / ShopApi / Impl: dropped resetShop
- ItemTagApi / Repository / Impl: renamed resetItemTag (/reset) ->
  idleItemTag (/idle)
- Utility: dropped scanUri(), extractItemTagInfoFrom(), NFC imports
- NatConstants: dropped SCAN_PATH, SCAN_PATH_CUSTOMER
- UserData: dropped didShowReadInstructionsTip,
  scanViewSelectedTabIndex, shouldFetchItemTagForShowTagInfoScan,
  shouldCompleteItemTagForCompleteScan
- shopSettingsNavigation: dropped ItemTagWriteRoute / itemTagWriteView
- Demo / test repos updated to match trimmed interfaces; obsolete tests
  removed (UtilityTest scanUri, CodedErrorTest NfcError, ItemTagDetailVMTest
  isLock, ShopDetailVMTest reset/didShowReadInstructionsTip)

### Config
- AndroidManifest.xml: removed NFC permission, android.hardware.nfc feature,
  NDEF_DISCOVERED intent-filter, singleTask launch mode
- build.gradle.kts / libs.versions.toml: removed compose-qr-code, capturable,
  lottie-compose
- user_preferences.proto: removed scan fields
- strings.xml: removed ~25 scan/NFC/QR strings; onboarding descriptions 1-13
  rewritten to generic "Welcome to the app." placeholder so OnboardingView
  still compiles (worth redesigning or deleting in a follow-up)

### Test plan
- [x] ./gradlew assembleDebug passes
- [x] ./gradlew test passes
- [x] ./gradlew spotlessCheck passes
- [x] ./gradlew lint passes
- [x] ./gradlew buildHealth passes
- [ ] Manual smoke test on device/emulator: 2 tabs visible (Shops /
  Settings), no Scan tab; sign-in works; ItemTag create / view detail
  placeholder / edit / delete flows work

* Phase 2A-3: Generic CRUD UI for ItemTag (#32)

Mirrors NativeAppTemplate-Android PR #40 (which mirrors iOS PR #50).
After this sub-phase, ItemTag is a generic parent-child CRUD UI:
Create/Edit accept any unicode/symbol name with multi-line description,
Detail screen shows a state badge + completed timestamp + Mark-as-completed/idled toggle,
the list card surfaces description preview + state.

Differences from the paid PR: this Free repo has no per-action permission
system (canCreateShops / canUpdateShops / canDeleteShops / canManageTags),
so all permission-gating in views and ViewModels is omitted — the FAB,
swipe-delete, edit toolbar, and state-toggle button are always shown.

### Data layer
- ItemTag.position: Int? -> Int = 0. Rails server's set_position_if_missing
  always populates this; client trusts the contract.
- ItemTagBodyDetail: dropped position (server auto-assigns).
- Data.getPosition() / ItemTag.getPosition(): now non-null Int.

### Rename maximumQueueNumberLength -> maximumNameLength
- Meta serial name maximum_queue_number_length -> maximum_name_length;
  default fallback 256 -> 100.
- Threaded through Permissions, UserData, user_preferences.proto,
  NatPreferencesDataSource, LoginRepository(+Impl), TestLoginRepository,
  DemoLoginRepository.

### ItemTag Create + Edit
- Validation relaxed: drop alphanumeric and count >= 2 checks. Valid name
  is 1 - maximumNameLength chars (any unicode/symbols/spaces).
- New description field: 0 - 1000 chars, optional, multi-line
  OutlinedTextField (minLines = 4).
  NatConstants.MAXIMUM_ITEM_TAG_DESCRIPTION_LENGTH = 1_000.
- Standard keyboard (no .Ascii).
- hasInvalidData checks both name AND description; Edit's also requires
  that name OR description changed.

### ItemTag Detail full rewrite
- HeaderRow: name + IdlingTag() / CompletedTag() badge.
- DescriptionSection: hidden when blank.
- CompletedAtRow: shown only when state == Completed.
- StateToggleButton: flips between Mark as completed and Mark as idled;
  uses MainButtonView; disabled while isToggling.
- ViewModel: new isToggling, completeItemTag(), idleItemTag(). Errors
  set uiState.message; success silently updates itemTag (matches the
  no-success-toast pattern from #31).

### ItemTag list card
- Headline: name + state badge.
- Supporting: description preview (2 lines, ellipsis) + completed
  timestamp when state == Completed.

### Date helpers
- Add ZonedDateTime.cardDateTimeString() and String.cardDateTimeString()
  to DateUtility.
- Card date format MMM dd yyyy -> yyyy/MM/dd.
- ShopDetailCardView and ItemTagListCardView use cardDateTimeString().

### Strings + constants
- New: name_label, description_label, completed_at_label,
  item_tag_name_placeholder, item_tag_name_is_invalid,
  item_tag_description_is_invalid, item_tag_name_help (format),
  item_tag_description_help (format), mark_as_completed, mark_as_idled.
- Removed queue-specific: tag_number, tag_number_is_invalid, zero_padding.

### Tests
- ItemTagCreateViewModelTest: new validation matrix (unicode/symbols,
  100/101 boundary, 1000/1001 description boundary).
- ItemTagEditViewModelTest: rewritten - unchanged-form invalid,
  description-only change valid, blank name invalid, unicode/symbols valid.
- ItemTagDetailViewModelTest: + completeItemTag / idleItemTag success cases.
- DateUtilityTest: + cardDateTimeString tests.

### Test plan
- [x] ./gradlew clean assembleDebug passes
- [x] ./gradlew test passes
- [x] ./gradlew spotlessCheck passes
- [x] ./gradlew lint passes
- [x] ./gradlew buildHealth passes
- [ ] Manual smoke test on emulator: sign in, create tag with
  "Buy milk 🥛" and multi-line description; mark complete; mark idled;
  edit description; delete

The test takes a long time to run, so I've commented it out.

spotlessCheck and Android Lint remain active.

* Reveal swipe actions from trailing (right) edge (#34)

Flip SwipeableItemWithActions so users drag the row right-to-left to
reveal action buttons, with the buttons sitting on the trailing (right)
edge instead of the leading (left) edge. Matches the iOS app's
swipeActions(edge: .trailing) and the platform-conventional
swipe-to-reveal gesture.

- Actions Row aligned to Alignment.CenterEnd of the wrapping Box
- Drag offset coerced to [-contextMenuWidth, 0f]
- Revealed anchor flipped to -contextMenuWidth; half-way fling threshold
  checks <= -contextMenuWidth / 2f

Public API (isRevealed, actions, onExpanded, onCollapsed, content,
modifier) is unchanged, so both call sites pick up the new direction
with no edits:
- ShopDetailView — Complete / Idle actions on item-tag rows
- ItemTagListView — Delete action on item-tag rows

* Drop maximum_name_length; remove How-To-Use from Settings (#35)

Two unrelated substrate-v2 cleanups bundled here.

## 1. Drop maximum_name_length from permissions; move to NatConstants

The server no longer sends maximum_name_length in /shopkeeper/permissions;
the client already tolerated its absence via a default. Promote the value
to a constant and drop the dead plumbing.

### Stop reading maximum_name_length from /shopkeeper/permissions
- Meta: drop the @SerialName("maximum_name_length") field.
- Permissions: drop getMaximumNameLength() helper.
- UserData: drop maximumNameLength field.
- user_preferences.proto: reserved 23 (was maximum_name_length) so the
  wire number isn't reused.
- NatPreferencesDataSource: drop the read in the userData mapping, the
  write in setPermissions, and the getMaximumNameLength() flow.
- LoginRepository (interface + impl + DemoLoginRepository +
  TestLoginRepository): drop getMaximumNameLength().

### Move maximumNameLength to NatConstants
- NatConstants: add MAXIMUM_ITEM_TAG_NAME_LENGTH = 100.
- ItemTagCreateViewModel + ItemTagEditViewModel:
  - UiState.maximumNameLength default now reads the constant.
  - Drop the loginRepository constructor param — it was only used for
    getMaximumNameLength().
  - ItemTagCreateViewModel.reload() simplifies to a state reset.
  - ItemTagEditViewModel.fetchData() drops the combine() pairing the
    item-tag flow with the maximum-name-length flow.
- Tests rewritten to drop the now-removed loginRepository wiring and
  the dead .copy(maximumNameLength = 100) calls; new
  maximumNameLength_matchesConstant tests assert against the
  NatConstants value (100).

## 2. Remove "How To Use" entry from Settings

Drop the SettingsView list item linking to myturntag.com/how — a
queue-product help page that no longer matches the substrate-v2
generic CRUD app surface.

The string resource (R.string.how_to_use), the
NatConstants.HOW_TO_USE_URL constant, and the OnboardingView call site
are left in place because they are still wired and may be repurposed.

* Add client-side length caps + truncation for Shop name/description (#36)

Mirror the ItemTag pattern (PR #35) for Shop. Server has no caps on Shop
name/description; this is a client-only UX guard.

### Changes
- NatConstants: MAXIMUM_SHOP_NAME_LENGTH = 100,
  MAXIMUM_SHOP_DESCRIPTION_LENGTH = 1_000.
- strings.xml: new shop_name_is_invalid, shop_description_is_invalid,
  shop_name_help, shop_description_help (parametric).
- ShopCreateViewModel + ShopBasicSettingsViewModel:
  - UiState gains maximumNameLength / maximumDescriptionLength
    (defaulted to the constants).
  - hasInvalidData() splits into hasInvalidDataName() +
    hasInvalidDataDescription(); the parent now ORs both.
  - updateName() / updateDescription() reject input over the cap
    (mirrors the existing ItemTagCreateViewModel /
    ItemTagEditViewModel Android pattern).
- ShopCreateView + ShopBasicSettingsView: switch supportingText to the
  two-line layout (always-visible help + conditional red "is invalid"
  line), matching ItemTagCreateView / ItemTagEditView. Description
  switches to heightIn(min=120) + minLines=4.
- Tests: maximumNameLength_matchesConstant /
  maximumDescriptionLength_matchesConstant, boundary tests at
  100 / 101 / 1000 / 1001 chars on both ShopCreateViewModelTest and
  ShopBasicSettingsViewModelTest.

* ShopDetailCardView: 2-column layout with description (#37)

* ShopDetailCardView: 2-column layout with description

Mirror iOS ItemTagListCardView's 2-column HStack pattern in
ShopDetailCardView so each item-tag row in ShopDetailView surfaces the
description alongside the name.

Layout:
- Left column (weight 1): name (titleLarge), description (bodySmall,
  max 2 lines, ellipsis) hidden when blank.
- Right column (minWidth 82dp, end-aligned): state tag — CompletedTag +
  completedAt for Completed; IdlingTag for Idled.

Matches iOS ItemTagListCardView's HStack { VStack(alignment: .leading)
[name, description] | Spacer | VStack(alignment: .trailing) [tag,
completedAt] } shape.

* Move description from ShopDetailCardView to ItemTagListCardView

Drop description block from ShopDetailCardView and revert to the
flatter row layout. Restructure ItemTagListCardView from ListItem to
a manual Row with a 2-column layout that surfaces the description.

* Drop unused tags-scanned count and howToUse; tighten ItemTag labels (#38)

Port iOS NativeAppTemplate-iOS#61 to Android:
- Drop `scannedItemTagsCount` from Attributes/Data and remove the
  "tags scanned by customers" stat from ShopListCardView.
- Add a left-aligned shop_detail_instruction header to ShopDetailView
  ("Swipe an item tag to change its status.").
- Swap OnboardingView's How-To-Use link for the Support Website link
  and trim onboarding from 13 to 8 descriptions; update placeholder
  strings to match the iOS copy.
- Normalize ItemTag labels: label_add_tag/add_tag_description/
  label_edit_item_tag/title_delete_item_tag and message_item_tag_*
  values now read "Item Tag" / "Item tag" consistently.
- Drop unused HOW_TO_USE_URL, R.string.how_to_use, R.string.learn_more.

* Slim onboarding to 4 slides and add ImageOrientation enum (#39)

Mirrors NativeAppTemplate-iOS#63 / NativeAppTemplate-Android#52: drops
slides 5-8, replaces descriptions with neutral placeholders, and
introduces an ImageOrientation enum so slides drive their own
bottom-padding instead of a Bool. View now reads the slide list from
the ViewModel rather than a hard-coded count.

Also swaps SignUpOrSignInView from ic_overview1_slim to a dedicated
ic_hero image and prunes unused overview drawables.

Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Add tests for Onboarding model, MainActivityViewModel, AuthInterceptor (#40)

Mirrors NativeAppTemplate-Android#53. Covers three previously-untested
areas:
- Onboarding data class + ImageOrientation enum (defaults, equality,
  enum entries).
- MainActivityViewModel uiState mapping (Loading, Success, isLoggedIn
  reflection) and the didShowTapShopBelowTip toggle persisting through
  the repository.
- AuthInterceptor header injection (with/without auth, base headers,
  URL preservation), using an in-test RecordingChain so the test runs
  as a plain JVM unit test.

TestLoginRepository.setDidShowTapShopBelowTip now mirrors the other
setters and updates the user-data flow so the persistence test can
observe it.

* Drop NFC-removal leftovers and tighten a few obvious patterns (#41)

- Delete CustomerScannedTag composable (dead since NFC/scan removal).
- Remove stale TODO marker in ShopDetailCardView left over from the
  schema-v2 drop of scanState/customerReadAt.
- Collapse NatConstants.baseUrlString into an expression-bodied
  function.
- Drop the redundant intermediate Flow vals (and now-unused imports)
  inside MainActivityViewModel.updatePermissions.

Mirrors NativeAppTemplate-Android#54.

* Fix dead password tests and add ItemTag whitespace-name regression tests (#42)

Two bugs in test assertions found while auditing validators:

1. Three password tests in SignInEmailAndPasswordViewModelTest and
   SignUpViewModelTest called hasInvalidDataEmail() instead of
   hasInvalidDataPassword(). Email is blank by default in those setups,
   so assertions passed for the wrong reason and the password rules
   were never actually exercised. Pointed them at hasInvalidDataPassword().

2. Added whitespaceOnlyName_isInvalid regression tests for both
   ItemTagCreateViewModel and ItemTagEditViewModel to lock in the
   isBlank() name validation already in place.

Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Remove dead code across utils and designsystem (#43)

- Drop shareImage / toUriCompat / isAlphanumeric from Utility (no
  production callers; deletes the matching tests)
- Drop cardTimeAgoInWordsDateString from DateUtility (unused, was the
  only consumer of android.text.format.DateUtils)
- Delete Tint.kt (TintTheme / LocalTintTheme) — provided by NatTheme
  but never read anywhere
- Drop successContainer / onSuccessContainer from CustomColorScheme
  and the now-orphaned Teal10 / Teal30 / Teal90 color tokens

Net: 7 files touched, 110 lines deleted. No production behavior changes.

Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Clean up legacy Number Tag/NFC artifacts and tighten utilities (#44)

- Remove leftover terminology and dead code from the previous "Number
  Tag" / NFC / QR-image feature set: README copy, NATA-3xxx error code
  row in CLAUDE.md, and the unused FileProvider declaration plus its
  filepaths.xml resource.
- Tighten validation messaging and small utilities: clarify item tag
  validation error messages, drop unused card date/time string overloads
  (production only uses String.cardDateTimeString), and rename
  validateEmail -> isValidEmail to match the is* boolean-predicate
  convention.

* Move phase2 prestep number-tag-rename doc out of repo

Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

* Normalize substrate naming to single NativeAppTemplate stem (#45)

Rename all `Nat`-prefixed Kotlin symbols to `NativeAppTemplate*`
(NatApp, NatAppState, NatConstants, NatPreferencesDataSource, NatNavHost,
NatAlertDialog, NatBackground, NatBottomBar, NatDispatchers,
NatNavigationBar*, NatOkHttpClient, NatPreferences, NatTheme,
NatTypography, plus rememberNatAppState) and rename the 8 corresponding
source files.

Rename Compose theme styles `Theme.Nat` and `Theme.Nat.Splash` (and the
`NightAdjusted.Theme.Nat` parent) to the `Theme.NativeAppTemplate.*`
family in themes.xml, values-night/themes.xml, and AndroidManifest.xml.

Rename the three Gradle properties `NATEMPLATE_API_{DOMAIN,PORT,SCHEME}`
to `NATIVEAPPTEMPLATE_API_*` in app/build.gradle.kts, README.md, and
CLAUDE.md.

Rename the `NATA-XXXX` error-code prefix to `NATIVEAPPTEMPLATE-XXXX`
across ApiException.kt, AppError.kt, CodedErrorTest.kt, CLAUDE.md, and
CHANGELOG.md.

Goal: every reference to the product uses one canonical stem
(`NativeAppTemplate`) so the upstream substrate renamer's
`NativeAppTemplate -> <slug-pascal>` rename pair handles every
occurrence in one rule. After this PR, `rg "Nat[A-Z]|NATEMPLATE|NATA-"`
returns zero matches outside `.git/` and `docs-private/`.

Set them in `~/.gradle/gradle.properties` (user-global, per-developer); the same config then works from both the terminal and the IDE. Falls back to `https://api.nativeapptemplate.com` when unset. One-off override: `./gradlew -PNATIVEAPPTEMPLATE_API_DOMAIN=... assembleDebug`.
