feat(tests): enhance test coverage and error handling across various components

- Added a test case in CrowdSecConfig to show improved error message when preset is not cached.
- Introduced a new test suite for the Dashboard component, verifying counts and health status.
- Updated SMTPSettings tests to utilize a shared render function and added tests for backend validation errors.
- Modified Security.audit tests to improve input handling and removed redundant export failure test.
- Refactored Security tests to remove export functionality and ensure correct rendering of components.
- Enhanced UsersPage tests with new scenarios for updating user permissions and manual invite link flow.
- Created a new utility for rendering components with a QueryClient and MemoryRouter for better test isolation.
- Updated go-test-coverage script to improve error handling and coverage reporting.
