feat: unlock 1080P+ on Android via DASH streaming

- getPlayUrl uses fnval=16 (DASH) on Android, keeping fnval=0/html5 for iOS/web
- New utils/dash.ts builds a valid DASH MPD from Bilibili's segmentBase ranges
  and returns it as a data: URI for ExoPlayer consumption
- NativeVideoPlayer selects DASH path (type='mpd') or durl fallback automatically
- Extend PlayUrlResponse types with DashVideoItem/DashAudioItem/DashSegmentBase
