feat: add CrowdSec API key status handling and warning component

- Implemented `getCrowdsecKeyStatus` API call to retrieve the current status of the CrowdSec API key.
- Created `CrowdSecKeyWarning` component to display warnings when the API key is rejected.
- Integrated `CrowdSecKeyWarning` into the Security page, ensuring it only shows when relevant.
- Updated i18n initialization in main.tsx to prevent race conditions during rendering.
- Enhanced authentication setup in tests to handle various response statuses more robustly.
- Adjusted security tests to accept broader error responses for import validation.
