add auto-review button that approves every high-confidence pending item

one-click for the common case: anything whose language came from
radarr/sonarr (confidence='high') is trusted enough to skip manual
review. low-confidence items stay pending.

- POST /api/review/auto-approve filters on rp.confidence='high' and
  enqueues audio jobs through the same dedup-guarded helper
- ColumnShell now takes actions[] instead of a single action, so the
  Review header can show Auto Review + Skip all side by side
