fix(mirror): add max auth request age configuration (#9812)

# Which Problems Are Solved

The `auth.auth_requests` table is not cleaned up so long running Zitadel
installations can contain many rows.

The mirror command can take long because a the data are first copied
into memory (or disk) on cockroach and users do not get any output from
mirror. This is unfortunate because people don't know if Zitadel got
stuck.

# How the Problems Are Solved

Enhance logging throughout the projection processes and introduce a
configuration option for the maximum age of authentication requests.

# Additional Changes

None

# Additional Context
