Validate a referral (bonus) code: whether it exists and whether it has been used up. The sign-up screens call this before an account exists, so no authentication is required; a bearer token, if sent, is ignored. Checks are budgeted per caller address (60 per 10 minutes) and across all callers; over budget the response is 429 with a Retry-After header.
