- Introduced `SandboxRiskDialog` to prompt users about risks when running outside a containerized environment.
- Added `SandboxRejectionScreen` for users who deny the sandbox risk confirmation, providing options to reload or restart the app.
- Updated settings view and danger zone section to manage sandbox warning preferences.
- Implemented a new API endpoint to check if the application is running in a containerized environment.
- Enhanced state management to handle sandbox warning settings across the application.
