push verified=1 to the UI via a plan_update SSE event

the ✓✓ write was landing in the db but never reaching the browser.
job_update fires once at job completion (card renders ✓, verified=0),
then handOffToJellyfin takes ~15s to refresh jellyfin + re-analyze +
UPDATE review_plans SET verified=1. no further sse, so the pipeline
page never re-polled and the card stayed at ✓ until the user
navigated away and back.

new plan_update event emitted at the end of handOffToJellyfin. the
pipeline page listens and triggers the same 1s-coalesced reload as
job_update, so the done column promotes ✓ → ✓✓ within a second of
jellyfin's verdict landing.
