fix: clear aborted playback state, fix overlay passthrough, and guard du

- Reset app_managed_playback_pending on lifecycle cleanup to prevent state leak into next item
- Record visible overlay action only after command succeeds, not before
- Non-native passive overlay now always click-through on re-show (fix isNonNativePassiveOverlay ordering)
- Defer activeParsedSubtitleMediaPath assignment until after prefetch completes
- Move autoplay gate release into the hide branch of toggleVisibleOverlay
- Clear active Jellyfin playback when stopping media that never loaded
- Reset managed subtitle delay and delay key when no external tracks are available
- Await async removeDir in subtitle cache cleanup
- Guard duplicate delete clicks in MediaDetailView and SessionsTab with refs
- Escape key in DeleteConfirmDialog now calls stopPropagation and stopImmediatePropagation
