Adds tag filtering and custom filters to the Movies and Series grids. Custom filters work like the ones in the Radarr and Sonarr web interface.

What's new

• Tag filter: a Tag picker in the filter menu, next to Root Folder.
• Custom filters: the filter menu lists the server's custom filters (/api/v3/customfilter, type movieIndex for Radarr and series for Sonarr) together with filters saved on the device.
  • A selected filter combines with the preset filter, the folder and the tag; an item must match all of them.
  • Filters with conditions Ruddarr can't check are marked with a warning, and those conditions are kept untouched when the filter is saved.
• Manage Filters sheet: create, edit, duplicate and delete filters. Each row shows a short summary of its conditions.
• Condition builder:
  • Fields are grouped into Status, Library, Dates, Ratings and Metadata, and each field offers the operators and values the web interface does.
  • Section headers read as sentences, e.g. "Added in the last 30 days".
  • The editor shows a live "Matches N of M movies" count.
• Saved in: server / This Device: saving to the server makes the filter show in the web interface. Moving a filter off the server asks for confirmation first.
• Active filters: shown as chips above the grid. Each chip clears its own filter.

How matching works

CustomFilter.matches follows the web interface's client-side rules from the Radarr develop and Sonarr v4 frontends:

• Conditions are combined with AND.
• Array values mean "any of", or "all of" for the negative operators.
• === is strict; string checks ignore case.
• Relative and absolute dates are handled, and so are the per-key predicates, e.g. ratings ×10, episode progress, missing seasons and seasons monitored status.

Keys that need data the app doesn't decode yet are treated as unsupported:

• Radarr: keywords, collection, release groups, file qualities, original title, release date and cutoff unmet.
• Sonarr: release groups and the v5-only keys.

Notes

• New code: the models are in Models/CustomFilters, the views in Views/Shared/CustomFilters. The Movies and Series views get small additions.
• Tests: Tests/CustomFilterTests.swift covers decoding, round-trips, matching rules and dates. The Tests target compiles three model files, added as membership exceptions in the project file.
• Preview data: custom-filters.json includes an unsupported filter and a filter of another type, which must be filtered out.
• Localisation: new strings use String(localized:) / Text, but Localizable.xcstrings isn't updated yet. Building in Xcode will add them.
• Changelog: CHANGELOG.md and WhatToTest have entries under Unreleased.

Testing

• Tests: all 273 pass on macOS. SwiftLint is clean.
• Simulator and Mac: checked with the mock API on iPhone 17 Pro and iPad Pro 11" simulators and on macOS: the menu, chips, Manage sheet, editor, saving to the device and the server, and unsupported filters.
• Device: installed on an iPhone 15 Pro Max.

If you want to open a PR that's not 3000 added lines and a minimal implantation of just displaying filters that are read-only from *arr, I'll take a look at it.
