feat: add sandbox environment checks and user confirmation dialogs

- Introduced a new endpoint to check if the application is running in a containerized environment, allowing the UI to display appropriate risk warnings.
- Added a confirmation dialog for users when running outside a sandbox, requiring acknowledgment of potential risks before proceeding.
- Implemented a rejection screen for users who deny sandbox risk confirmation, providing options to restart in a container or reload the application.
- Updated the main application logic to handle sandbox status checks and user responses effectively, enhancing security and user experience.
