Add likes, follows and playlist visibility; redesign web-player UI

Backend: - New Likes feature (toggle/get liked tracks) and endpoints - User follow/unfollow, listening stats, public user profile - Playlist visibility (public/private) support - Various auth and DTO/response adjustments to support the above Frontend (web-player): - New design system pass: theme tokens/mode (light/dark), glass menu, tabs bar, player dock/extras/queue components, mix tiles, artist link - New routes: Liked, public user profile (/u/[id]), likes API proxy - Search refactor: shared SearchBox component used by TopBar and MobileHeader (search now reachable on mobile), live results as you type instead of requiring Enter, dropped the "Buscando…" quick-result preview - Removed now-unused components (MobileNav, CoverBadge, MixBentoTile, PlayPauseOverlay, SuggestionsTable, userDirectory) - Design handoff reference docs added under web-player/design_handoff_musify_player and web-player/docs/design-system-refactor-plan.md
