Add dynamic log level adjustment and "type" field to auth files response

- Introduced `SetLogLevel` utility function for unified log level management.
- Updated dynamic log level handling across server and watcher components.
- Extended auth files response by extracting and including the `type` field from file content.
- Updated management API documentation with the new `type` field in auth files response.
