fix(api): restore root logger configuration in middleware

Re-introduces the root logger configuration, which was lost during the refactor away from `lib/server.dart`.

The configuration is now placed in the root middleware and uses a flag to ensure it only runs once per application lifecycle. This is critical for enabling log output for all subsequent processes, including dependency initialization and error handling.
