feat(auth): 12-character minimum, 72-byte maximum and breach check for new passwords

- New passwords (create user, admin reset, own change) need at least 12
  characters (ASVS 2.1.1) and may not exceed 72 bytes, which bcrypt would
  silently cut off.
- They are checked against Have I Been Pwned with k-anonymity (only the
  first 5 SHA-1 characters leave the server, padded responses); an
  unreachable service is logged and does not block. PASSWORD_BREACH_CHECK
  =false disables it for offline deployments.
- Login accepts existing passwords as before, capped at 256 characters to
  bound anonymous bcrypt work.
- Password fields in the UI say the rule up front.
