anti 5d883466a2 fix(api): advertise 429 on every operation in OpenAPI
SlowAPI middleware can short-circuit any request with 429 once a
per-route or per-IP rate limit fires (e.g. POST /api/v1/auth/login is
capped at 10/5min). The OpenAPI spec did not declare 429 on any
operation, so schemathesis flagged legitimate rate-limit responses as
RejectedPositiveData / status-code-nonconformance failures.

Override app.openapi to inject a generic 429 response object on every
HTTP operation in the generated schema. Add a contract test that fails
if any operation drops the 429 advertisement.

"""OpenAPI must advertise 429 on every operation.
SlowAPI can return 429 from any rate-limited route at any time. If the
schema doesn't list it, schemathesis (and any other contract-driven
client) treats a legitimate rate-limit response as a contract violation.
