fix: queue shows 0:00 duration for sourced tracks

YouTubeEngine passed track duration in seconds while
SpotubeAudioSourceMatchObject.fromJson interprets `duration` as
microseconds, so durations collapsed to ~0 and the queue displayed 0:00.

- lib/services/metadata/metadata.dart: send duration in microseconds
  (search() and getVideo() callbacks)
- lib/components/track_tile/track_tile.dart,
  lib/modules/player/player_queue.dart: add resolveMissingDuration so
  the queue actively resolves the sourced track's real duration when
  the track's own metadata duration is effectively zero

Fixes #3021
