docs: record RAGcore search/answer wiring deployment to production

Deployed a2905cc to the live RAGcore instance (approved). Verified
the fix directly: POST /v1/search now returns 401
AUTHENTICATION_REQUIRED instead of the old permanent 503
SEARCH_UNAVAILABLE, proving the endpoint reaches real request
handling. A full authenticated /v1/answers call with a real grounded
answer is still outstanding -- the previously-issued production
credential's raw token was never persisted anywhere retrievable, and
issuing a fresh one needs the RAGcore admin UI, not attempted this
round.
