Add TempUrl signature validation to local storage

Implemented local storage-based file handling with TempUrl signature validation for upload and retrieval. Added validation checks for parameters like max file size/count, expiration, and signature integrity. Included unit tests for TempUrl signature validation and adjusted configuration for local storage.
