feat(catchup): resolve persisted M3U archive intent through catalog access

[MrFr3di]

Refs #285, parent #184. Non-draft replacement for #302; head/base/tree are unchanged.

Scope

Completes the remaining M3U Slice E catalog/access integration only:

• provider-neutral PlaybackArchiveRequest / typed archive resolution in catalog:api;
• M3U adapter in catalog:refresh delegates to the already-accepted M3uCatchupTransportResolver;
• persisted active catchupMode/source/days/correction are supplied by RoomPlaybackCatalog.resolveIntent() only for explicit catch-up intents;
• materialized archive locator passes through the existing credential/exact-origin playback access coordinator before becoming a ResolvedPlaybackRequest;
• normalized ResolvedPlaybackTimeline is carried with the resolved request;
• PlaybackIntent.Live and existing resolveVariant() stay on the legacy Live path and cannot select an archive template;
• app Hilt composition installs the M3U archive adapter.

No Room migration, Media3 URL parsing, Guide UI, Xtream catch-up, DVR, local-timeshift, second player/seek/retry owner, new provider framework, or third persistent AVD.
