The post-delete auto-select effect re-picked the just-deleted id from the still-stale
playlists cache, so its detail lingered. Select the next remaining playlist directly on
delete (or null), drop the deleted detail from the cache, and make the effect re-validate
the selection against the current list (clear when empty, reselect when the current id is
gone). Also fix the header title showing "Channel manager" on the Playlists page.
