feat: Implement storage provider management functionality

- Added new routes and handlers for managing storage providers, including creation, editing, and deletion. - Introduced a new StorageProvider form component for user input. - Enhanced the database schema to support storage provider references in transfer configurations. - Implemented encryption for sensitive fields in storage provider data. - Added tests for storage provider API endpoints and integration with the database. - Updated frontend components to support storage provider selection and testing.
