feat: add search filters for Deezer default search

- Add filter parameter to Deezer SearchAll (track/artist/album/playlist)
- When filter is specified, increase limit for that type only
- Add default Deezer filters when not using extension search
- Reduce artist limit from 5 to 2 in home search results
- Filter bar now shows for both extension and default Deezer search
- Fix filter not being passed correctly during search (preserve filter state)
