Refactor logging settings to use DittoLogLevel directly

- Replaced `LoggingOptions` with `DittoLogLevel` from the Ditto SDK, removing the reference to custom wrapper type.
- Added `isLoggingEnabled` state to separately track logging enablement alongside log levels.
- Updated `SettingsModel`:
  - Refactored `storedLoggingOption` to migrate legacy `UserDefaults` values to `DittoLogLevel` and clean up old keys.
  - Simplified future storage/retrieval to use `DittoLogLevel` directly.
- Modified `SettingsView` constructor to take a `Ditto` instance instead of `LoggingOptions`.

These changes simplify logging logic, align with the updated Ditto SDK, and ensure backward compatibility.
