[enhancement]: better version checks for lyrics, Navidrome (#529)

- Actually make serverfeatures partial
- Navidrome: only set multiple structured lyrics if extension exists
- Navidrome/Subsonic: minor type checking of OS extension (Navidrome implementation detail)
- Jellyfin: add separate knob for lyrics. Note, this should also probably be behind some version check...
