Adds time-based activity tracking for scenes played via DLNA, enabling
play count, play duration, and resume time tracking similar to the
web frontend.
Key features:
- Uses existing 'trackActivity' UI setting (no new config needed)
- Time-based tracking (elapsed session time / video duration)
- 5-minute session timeout to handle aggressive client buffering
- Minimum thresholds before saving (1% watched or 5 seconds)
- Respects minimumPlayPercent setting for play count increment
Implementation:
- New ActivityTracker in internal/dlna/activity.go
- Session management with automatic expiration
- Integration via DLNA service initialization
Limitations:
- Cannot detect actual playback position (only elapsed time)
- Cannot detect seeking or pause state
- Designed for upstream compatibility (no complex dependencies)
