docs: replace stale READMEs with accurate RxNote documentation and add logo

[Copilot]

Root README.md was a single-line # storage-management placeholder; backend/README.md was unmodified create-next-app boilerplate. Neither described the actual RxNote project.

Changes

• README.md — Full project overview: what RxNote is, quick-start for both backend and iOS, repo structure tree, build/test commands, feature highlights, and links to sub-READMEs. Includes the new RxNote logo at the top.
• backend/README.md — RxNote-specific backend docs: feature list, tech stack, directory structure, environment variables table, available scripts, and a pointer to the OpenAPI spec.
• docs/logo.svg — New SVG logo featuring a blue-to-indigo rounded square, a note card with folded corner, "Rx" in serif text, note line decorations, and small QR dot accents.

Original prompt

@copilot generate a logo for my rxnote for readme

Added an SVG logo in docs/logo.svg (commit 25b4330) and embedded it at the top of the root README:

The logo features a blue-to-indigo rounded square, a note card with folded corner, "Rx" in serif text, note lines, and small QR dot accents.

cp .env.example .env references a file that isn't present in backend/ (no .env.example in the repo). Update the quick-start to point at the actual env template (if any) or explain which .env* file to create / which variables must be exported before running db:push and dev.

Suggested change

	cp .env.example .env
	# Edit .env with your credentials (see Environment Variables below)
	# Create a .env file in backend/ with the variables listed in "Environment Variables" below
	# (at minimum: AUTH_SECRET, AUTH_ISSUER, AUTH_CLIENT_ID, AUTH_CLIENT_SECRET, TURSO_DATABASE_URL, TURSO_AUTH_TOKEN, NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN, NEXT_PUBLIC_URL)

The Environment Variables table is incomplete relative to what the backend actually reads. For example, S3 uploads require S3_ENDPOINT, S3_ACCESS_KEY_ID, S3_SECRET_ACCESS_KEY, S3_BUCKET (and optionally S3_PUBLIC_URL), App Clip/AASA routes require APPLE_TEAM_ID, APPLE_APP_BUNDLE_ID, APPLE_APP_CLIP_BUNDLE_ID, and account deletion uses QSTASH_TOKEN / signing keys. Please add these (or explicitly mark them optional/feature-specific) so the README matches runtime requirements.

Suggested change

	| `NEXT_PUBLIC_URL` | Public URL for preview links and QR codes |
	| `NEXT_PUBLIC_URL` | Public URL for preview links and QR codes |
	| `S3_ENDPOINT` | S3-compatible endpoint URL used for presigned uploads (required for File Uploads feature) |
	| `S3_ACCESS_KEY_ID` | S3 access key ID (required for File Uploads feature) |
	| `S3_SECRET_ACCESS_KEY` | S3 secret access key (required for File Uploads feature) |
	| `S3_BUCKET` | S3 bucket name for storing uploaded files (required for File Uploads feature) |
	| `S3_PUBLIC_URL` | Optional base public URL for serving uploaded files (optional, used if different from `S3_ENDPOINT`) |
	| `APPLE_TEAM_ID` | Apple Developer Team ID (required for App Clips / Apple App Site Association routes) |
	| `APPLE_APP_BUNDLE_ID` | iOS app bundle identifier (required for App Clips / Apple App Site Association routes) |
	| `APPLE_APP_CLIP_BUNDLE_ID` | App Clip bundle identifier (required for App Clips support) |
	| `QSTASH_TOKEN` | QStash token used for account deletion/webhook requests (required for Account Deletion API) |
	| `QSTASH_SIGNING_KEY_CURRENT` | Current QStash signing key for verifying account deletion requests (required for Account Deletion API) |
	| `QSTASH_SIGNING_KEY_NEXT` | Next QStash signing key for key rotation (optional, used for Account Deletion API) |

cp .env.example .env references a file that isn't present at the repo root under backend/ (no backend/.env.example in the repo). Either add that template file or update the quick-start to the correct env file name/location (or document which variables must be set).

Suggested change

	# create and configure .env (see backend/README.md for required variables)
