peter b7ce1d467c fix(playlists): item writes lock the list first; one bulk pull per user; the claim on its own connection
- Every playlist item write (add, remove, move, reorder, rename; Plex remove and remove-bulk) row-locks
  the playlist before it touches an item, a move both lists in id order: remove beside reorder was a
  deadlock, and two adds of one video a unique-key 500.
- The scheduled mirror refresh re-reads dirty under that lock, so an edit made during its YouTube calls
  is not replaced by YouTube's order.
- A user's bulk pull holds a per-user advisory claim: two at once created duplicate mirrors. The manual
  sync answers 409 sync_all_busy instead of '0 synced', and like the re-pull spends its cooldown only
  on a pull that runs.
- Deleted mirrors are committed at once, not only when a later list commits.
- The claims open an unpooled connection of their own instead of a third pooled one per push.

"""An action YouTube refuses answers a 422 the UI can translate — never a raw 500 — and says what the
user can do about it (`routes/_common.youtube_refusal`). E9 F1: the two manual syncs had no handler
at all, so a quota or transport failure opened the blocking "Server error" dialog."""
