fix: respect lockout policy on password change (with old password) and add tar pit for checks

# Which Problems Are Solved

While the lockout policy was correctly applied on the session API and other authentication and management endpoints , it had no effect on the user service v2 endpoints.

# How the Problems Are Solved

- Correctly apply lockout policy on the user service v2 endpoints.
- Added tar pitting to auth factor checks (authentication and management API) to prevent brute-force attacks or denial of service because of user lockouts.
- Tar pitting is not active if `IgnoreUnknownUsername` option is active to prevent leaking information whether a user exists or not.

# Additional Changes

None

# Additional Context

- requires backports

* cleanup
