feat(player): add media segment skip with all 5 Jellyfin segment types

Closes #1312
Fixes #883

Adds a unified segment skip feature using the Jellyfin 10.11+
MediaSegments API. Replaces the legacy intro-only and credits-only
hooks with a single useSegmentSkipper hook covering Intro, Outro,
Recap, Commercial, and Preview.

Three modes per segment type: none, ask (show button), auto (skip
automatically). A dedicated submenu under Playback Controls keeps
the main settings page uncluttered.

Highlights:
- utils/segments.ts uses getMediaSegmentsApi from @jellyfin/sdk so
  includeSegmentTypes is serialized as repeated keys instead of the
  bracket-encoded form axios produces by default (the Jellyfin
  server silently ignored the filter otherwise). Falls back to the
  pre-10.11 intro-skipper / chapter-credits plugin endpoints when
  the new API is unavailable.
- hooks/useSegmentSkipper.ts stores seek and haptic in refs so the
  auto-skip effect does not re-run when their identities change
  (useHaptic returns a fresh no-op every render when disabled).
  currentSegment is memoized; the per-segment-type setting lookup
  uses a small map instead of a switch IIFE.
- components/video-player/controls/Controls.tsx prioritizes
  Commercial > Recap > Intro > Preview > Outro when multiple
  segments overlap and exposes the active type to BottomControls
  via skipButtonText.
- components/video-player/controls/BottomControls.tsx accepts the
  dynamic skipButtonText/skipCreditButtonText props.
- providers/Downloads/types.ts extends DownloadedItem with the
  three new segment buckets for offline playback.
- utils/atoms/settings.ts adds SegmentSkipMode and the five skip
  settings, defaulting to "ask".
- app/(auth)/(tabs)/(home)/settings/segment-skip/page.tsx renders
  the five dropdowns from a data table.
- translations/en.json and translations/fr.json add the new keys.
