feat: Add device storage and WiFi management functionalities

- Implemented storage configuration management in device_storage.go:
  - GetStorageConfigurations
  - GetStorageConfiguration
  - CreateStorageConfiguration
  - SetStorageConfiguration
  - DeleteStorageConfiguration
  - SetHashingAlgorithm

- Added unit tests for storage configuration operations in device_storage_test.go.

- Implemented WiFi management functionalities in device_wifi.go:
  - GetDot11Capabilities
  - GetDot11Status
  - GetDot1XConfiguration
  - GetDot1XConfigurations
  - SetDot1XConfiguration
  - CreateDot1XConfiguration
  - DeleteDot1XConfiguration
  - ScanAvailableDot11Networks

- Added unit tests for WiFi management operations in device_wifi_test.go.

- Updated types.go to include new structures for geo location and access policy.
