feat: three-dot context menu on song rows + search shows songs as rows

- Add ⋮ button to every song-item triggering the context menu (same as right-click)
- Show song-actions always visible on touch devices via @media (hover:none)
- Search results: songs now render as makeSongItem rows instead of cards
  (artists/albums remain as horizontal card rows)
- Fix Android app opening system settings on every launch after notification
  permission denial — now only redirects to settings once using notif_settings_shown flag
