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.
