Release v1.3.0: Multi-source downloads, audio analyzer resilience, mobile improvements

Major Features:
- Multi-source download system (Soulseek/Lidarr with fallback)
- Configurable enrichment speed control (1-5x)
- Mobile touch drag support for seek sliders
- iOS PWA media controls (Control Center, Lock Screen)
- Artist name alias resolution via Last.fm
- Circuit breaker pattern for audio analysis

Critical Fixes:
- Audio analyzer stability (non-ASCII, BrokenProcessPool, OOM)
- Discovery system race conditions and import failures
- Radio decade categorization using originalYear
- LastFM API response normalization
- Mood bucket infinite loop prevention

Security:
- Bull Board admin authentication
- Lidarr webhook signature verification
- JWT token expiration and refresh
- Encryption key validation on startup

Closes #2, #6, #9, #13, #21, #26, #31, #34, #35, #37, #40, #43
