video: isolated worker-orbs idle animation on the video dashboard

Port of webui/static/worker-orbs.js into video/video-worker-orbs.js — same
exact animation (physics/draw copied verbatim), but pointed at the video
dashboard header + the TMDB/TVDB enrich buttons + Manage Workers hub. Own
window.videoWorkerOrbs global, activated by the video side's page events;
music's orbs file is untouched and never learns about the video side.

video-enrichment.js feeds it real status as telemetry for the inbound pulses.
7s idle → floating orbs around the SoulSync logo, just like music.
