feat(artist): add Tributes section and improve album categorization

Major improvements to album categorization logic:

Detection improvements:
- Broadcasts: detect plural forms, "Radio Broadcasts", "The Beast Radio"
- Live albums: detect "Alive", city+year patterns (Seattle 1989, Tokyo 1986)
- Podcasts: detect "Report Episode X", single-track 20+ min releases
- Singles: 1-4 tracks (classic 45rpm), explicit markers in title

New Tributes section:
- Albums by different artists now go to "Tributes & Covers"
- Separates tribute/cover albums from legitimate artist content
- Keeps Others clean for compilations, B-sides, unofficial releases

Categorization priority:
1. Different artist -> Tributes
2. Broadcasts/bootlegs/podcasts -> Others
3. Compilations (greatest hits, B-sides) -> Others
4. Live albums -> Live
5. Studio albums (7+ tracks, 25+ min, deluxe) -> Discography
6. EPs/Singles (1-4 tracks, <15 min) -> EPs & Singles
