fix: check for 2fa even if not enforced

# Which Problems Are Solved

Zitadel enforces MFA if required by the organization's policy, but did not ensure in all cases, if a user voluntarily set it up.

# How the Problems Are Solved

Ensure 2FA/MFA is required in any call to Zitadel if set up by user even if policy does not require.

# Additional Changes

None

# Additional Context

- requires backports
