- Removed redundant `gin.SetMode(gin.TestMode)` calls from individual test files.
- Introduced a centralized `TestMain` function in `testmain_test.go` to set the Gin mode for all tests.
- Ensured consistent test environment setup across various handler test files.
- Added role-based middleware to various security handler tests to ensure only admin users can access certain endpoints.
- Created a new test file for authorization checks on security mutators, verifying that non-admin users receive forbidden responses.
- Updated existing tests to include role setting for admin users, ensuring consistent access control during testing.
- Introduced sensitive data masking in settings handler responses, ensuring sensitive values are not exposed in API responses.
- Enhanced user handler responses to mask API keys and invite tokens, providing additional security for user-related endpoints.
- Refactored routes to group security admin endpoints under a dedicated route with role-based access control.
- Added tests for import handler routes to verify authorization guards, ensuring only admin users can access import functionalities.
