They were registered in the manager modal (WORKERS) + status poll (SERVICES) but the
dashboard HEADER renders its own per-worker .video-enrich-container buttons (with the
floating orb animation) keyed by data-video-enrich, and the orb engine has its own
WORKER_DEFS list — neither had the new services, so trakt/tvmaze/anilist/dearrow/
wikidata were absent from the header.
Added a header button + tooltip block for each (matching the fanart/opensubtitles
pattern, accent colors consistent with the manager orbs) and the matching WORKER_DEFS
entries in video-worker-orbs.js. Status was already wired via the SERVICES list, so
they now animate + report in the header identically to the existing workers.
