fix(ui): drop gold-set card from /api/chair/pending — data/ excluded from image

The gold-set card read data/eval/gold-set.jsonl, but .dockerignore excludes
data/ from the build context, so the file is never in the container and the
card silently never rendered. Baking eval data into the image is the wrong
layering (data/ is runtime volumes). The gold-set review is a one-time task,
not a recurring chair queue, so it doesn't belong on the live board — it's
tracked via task #63 and reviewed directly with the chair. The board now
returns the 4 robust DB-backed gates (halachot, missing precedents, feedback,
qa_failed). Removes the best-effort file read + its unused Path import.
