fix: button focus ring, playlist reorder mode, edit modal mobile, backdrop-filter

- button:focus{outline:none} — removes the blue tap-highlight box in WebView
- Playlist reorder: replaced always-on drag handles with explicit 'Neu anordnen'
  mode. Handles only appear after tapping the button; a sticky Speichern/Abbrechen
  bar appears above the list. Touch drag is now fully supported. Context-menu
  (long-press) is blocked while reorder mode is active to prevent conflicts.
- styles.css: .pl-drag-handle always visible when pl-draggable (no hover needed)
- Edit modal footer: wrap buttons on small screens so Save doesn't overflow
- Edit modal overlay: remove backdrop-filter:blur — causes WebView compositor
  glitch where 3/4 of the modal disappears after returning from background
