Hartmut afabaa0b7a fix(security): prevent TOTP replay attacks and fix user enumeration in verifyTotp
Adds lastTotpAt timestamp to User model. After a successful TOTP validation,
the timestamp is recorded. Any reuse of the same code within the 30-second
window is rejected as a replay attack.

verifyTotp now returns a single generic UNAUTHORIZED error regardless of
whether the user ID is invalid or TOTP is not enabled, preventing enumeration
of user IDs and MFA status.
