feat: replace store game detail dialogs with full-screen activities

Replace the showDetailDialog() AlertDialog popups in GOG, Epic, and
Amazon store activities with dedicated full-screen detail Activities.

Changes:
- Add GogGameDetailActivity.java: full-screen GOG game detail with
  dark purple theme, cover art, info card (gen badge, developer, genre,
  description), actions card (install/uninstall/set-exe/copy/launch),
  and stubs for Updates, DLC, Cloud Saves sections
- Add EpicGameDetailActivity.java: full-screen Epic game detail with
  dark blue theme, inline Epic pipeline (token → manifest → download),
  actions card with progress tracking
- Add AmazonGameDetailActivity.java: full-screen Amazon game detail
  with dark amber theme, AmazonDownloadManager pipeline, exe scoring
- Modify GogGamesActivity: replace showDetailDialog() calls (list
  card click + grid tile long-press) with openDetailScreen() +
  startActivityForResult(REQ_GAME_DETAIL=1001); add onActivityResult()
  that calls applyFilter() on RESULT_REFRESH=100
- Modify EpicGamesActivity: same replacement pattern
- Modify AmazonGamesActivity: same replacement pattern
- Register all 3 new activities in patches/AndroidManifest.xml
