The `conf` object in `airflow.sdk.configuration` is lazily initialized via `__getattr__`. Importing it at module level in `cache.py` causes `ImportError` when the module is deserialized in a multiprocessing child process on Python 3.14. Moving the import into `SecretCache.init()` where it's actually used avoids this issue.
