chore: remove dead code to eliminate all compiler warnings

- Remove unused get_artist() (replaced by get_artist_page())
- Remove unused Format::label(), Format::all()
- Remove unused QwsTokenResponse and QwsToken structs
- Remove unused PlayerCommand::Seek (seeking uses atomics directly)
- Remove unused PlayerState::Stopped, TrackInfo::format
- Remove unused PlayerStatus::get_current_track()
