feat(adult): 🍿 collection detail view — clip checklist + offline download

Tapping a collection card on the Adult page now opens a detail view listing
every clip in that collection (goon, pmv, etc) instead of silently firing the
whole set at a host with nothing cached. Each row shows:
- queued state as a tickable checklist (build a session clip by clip)
- freshness / last-played
- offline-cached state, with a per-clip download-to-offline button

Plus a title filter (find e.g. a specific 'brain rot'/gooner clip), queue-all-
fresh, download-all-queued-offline, and play-queued. Downloads land in the
offline cache where the new star/trash row controls manage them. Quick-play the
old fire path stays on the card context menu.

Core: PornCollectionService.clips()/title() expose the full per-collection clip
list with freshness; PlaylistController gains single-item checklist queue ops
(isQueued/addToQueue/removeFromQueue) and pornClips().
