Editable local playlists get an Export/Sync to YouTube button (write-scope gated):
it fetches a dry-run plan, shows a confirm with the change counts, quota estimate
and divergence warning, then pushes. An 'unsynced changes' badge and an accented
YouTube icon mark linked playlists with local edits. Deleting a linked playlist
offers 'delete on YouTube too' vs 'here only'. Trilingual strings (HU/EN/DE).
