- UIRealmResource: add "info" sub-resource to get realm-related information, which is visible for ALL admins (users having any realm-management role); for now, only provide the information whether any user profile provider is enabled
- UIRealmResourceTest: test the new endpoint, including permissions check
- UserDataTable.tsx: use this resource to get the info whether user profile providers are enabled, instead of using the realm components resource (which requires "view-realm" permissions)
- .../cypress/e2e/users_attribute_search_test.spec.ts: add cypress test to test the attribute search with minimum access rights
- further small changes for reuse of components, test-code etc
Closes#27536
