fix: correct i18n mock in CrowdSec tests and silence query warning

- Added [ready: true](http://_vscodecontentref_/6) to [react-i18next](http://_vscodecontentref_/7) mock in CrowdSecBouncerKeyDisplay tests to prevent infinite loading state
- Mocked [getCrowdsecKeyStatus](http://_vscodecontentref_/8) in Security page tests to resolve "Query data cannot be undefined" warning
- Ensures all Security dashboard related tests pass reliably without console errors
