test(auth): freeze the cache clock in auth prefetch tests

The org cache entries written by prefetch_auth_objects carry the 5s
DEFAULT_IN_MEMORY_TTL. The first @log_db_metrics getter lazily imports
litellm.proxy.proxy_server, which on a cold CI runner can take longer
than 5s, so the org entry expired before get_org_object read it and the
getter fell through to the MagicMock database. Inject a frozen clock
into InMemoryCache so the test asserts the join, not import latency.
