fix: lyrics faster + title-only search fallback for metadata mismatches

- Android: add 6s HttpTimeout to LrcLibClient, wrap each step in withTimeoutOrNull
- Both: add title-only lrclib search (step 3) so "Sanctuary (Opening)" is found
  even when artist tag differs ("Utada" vs "Hikaru Utada")
- Web: reduce all timeouts 8s → 5s, extract bestMatch helper

Search order: lrclib exact → lrclib artist+title → lrclib title-only → NetEase
