Fix Android navigation and improve UI responsiveness

- Convert music category buttons from <button> to native <a> links for better Android compatibility
- Convert artist/album nested buttons in TrackList to <a> links to fix HTML validation issues
- Add event handlers with proper stopPropagation to maintain click behavior
- Increase library overview card sizes from medium to large (50% bigger)
- Increase thumbnail sizes in list view from 10x10 to 16x16
- Add console logging for debugging click events on mobile
- Remove preventDefault() handlers that were blocking Android touch events

These changes resolve navigation issues on Android devices where buttons weren't responding to taps. Native <a> links provide better cross-platform compatibility and allow SvelteKit to handle navigation more reliably.
