The filter only watched /api/auth/login 401 — leaving the forgot-password
endpoint open to:
- email enumeration (slow brute-force probing which addresses exist)
- password-reset brute-force against accounts whose addresses leak
Widens the failregex to /api/auth/(login|forgot-password) and adds 429 to
the status alternation so a future in-app rate-limiter response is also
caught by the jail (defense in depth).
CI assertions extended to cover both new dimensions plus a negative case
on an unrelated 401 endpoint (/api/documents) — pins that the widening
did not over-match.
