Redesign AniStream UI and fix Anime3rb scraping flow

[shinzero-code-test]

Summary

• Redesigned the Compose UI/UX and added watchlist/history/player settings improvements.
• Reworked Anime3rb Cloudflare handling to show a visible launch WebView, persist cookies/user-agent, sync WebView cookies before requests, and re-open verification when Anime3rb returns Cloudflare/403.
• Fixed Anime3rb search to request the live shape https://anime3rb.com/search?q=Code+Geass and parse both full .title-card and live .simple-title-card results.
• Fixed episode playback to default to the embedded Anime3rb/vid3rb WebView player with the cinema=760 iframe URL, avoiding audio-only direct stream picks unless the user explicitly selects direct sources.
• Added in-app trailer playback with a dedicated WebView trailer screen.
• Added Anime3rb category list screens/routes for Anime, TV, Movie, OVA, ONA, Specials, TV Specials, PV, CM, Music, and Other lists.
• Expanded details extraction/display with JSON-LD rating count, publish date, alternate names, genres, trailers, episodes, related titles, and existing metadata.

Review & Testing Checklist for Human

• Install the debug APK on a real Android device, clear/refresh the Anime3rb WebView session if prompted, then verify search for Code Geass uses the live search page and returns results.
• Open an episode and confirm video + audio render together in the embedded player; only test direct sources after confirming the embedded player works.
• Open a details page trailer chip and confirm it plays in-app.
• Open the new category chips on Home (Anime/TV/Movie/OVA/ONA/Special/etc.) and verify list pagination/details navigation.
• Open an anime details page and verify extra metadata such as rating count/date/alternate names/genres/trailers/episodes displays correctly.

Notes

Local verification passed: ./gradlew testDebugUnitTest, ./gradlew lintDebug, and ./gradlew assembleDebug. I still cannot run real Android visual/playback testing in this VM because there is no connected device/KVM and the emulator stays offline.

Runtime test results

Escalation: visual UI validation is blocked in this VM. There is no connected Android device, /dev/kvm is unavailable, GUI screenshots fail because the X display is unavailable, and the software headless emulator stayed offline until timeout. I did not record or claim visual assertions passed.

• Passed — APK artifacts exist under app/build/outputs/apk/debug/, including app-universal-debug.apk.
• Passed — CI is green: 2/2 build-debug-apk checks passed.
• Passed — https://anime3rb.com is reachable from the VM.
• Untested — Home/Library/Settings visual redesign, due to no usable Android runtime.
• Untested — Settings skip-intro + cinema-mode interaction, due to no usable Android runtime.
• Untested — Details → Player flow and Player preference chips, due to no usable Android runtime.

Evidence:

/dev/kvm: No such file or directory
adb devices: List of devices attached (empty)
emulator -list-avds: anistream_api35
CI: 2 passed, 0 failed, 0 pending
