Payload: Unauthenticated account-lockout denial of service

### **Impact** An unauthenticated attacker who knows an account’s email address or username could trigger Payload’s account lockout mechanism and prevent that user from signing in. You are affected if: * Using an affected Payload version with an auth-enabled collection that uses local authentication and account lockout. Applications that do not use Payload local authentication are not affected. ### **Patches** Successful password resets now clear the account’s lockout state. The forgot-password flow also enforces a configurable minimum interval between reset emails, which defaults to 15 seconds. Users should upgrade Payload packages to `>= 3.90.0` or `>= 4.0.0-canary.34`.
