POST /entities/{id}/promote now wraps the promote_entity call in
try/except ValueError → HTTPException(400). Previously the new
V1-0 provenance re-check raised ValueError that the route didn't
catch, so legacy no-provenance candidates promoted via the API
surfaced as 500 instead of 400.
Matches the existing ValueError → 400 handling on POST /entities
(api_create_entity at routes.py:1490).
Test: test_api_promote_returns_400_on_legacy_no_provenance inserts
a pre-V1-0 legacy candidate directly, POSTs to the promote route,
asserts 400 with the expected detail, asserts the row stays
candidate.
Test count: 547 -> 548. Full suite green in 72.91s.
Closes R14.
