Refactor and enhance device management and authentication features

- Updated the `reverse_dhivehi_string` function to correct the range for combining characters.
- Added new device handling in the health check view and integrated the `add_new_devices_to_omada` task.
- Improved date handling in `CreateTemporaryUserView` to ensure proper string conversion.
- Enhanced OTP sending by converting mobile numbers to strings.
- Implemented MAC address validation in the `Device` model using a custom validator.
- Removed unnecessary fields from the `CreateDeviceSerializer`.
- Normalized MAC address format in the `DeviceListCreateAPIView`.
- Updated the `djangopasswordlessknox` package to improve code consistency and readability.
- Added migration to enforce MAC address validation in the database.
