Fix flanky tests (#17665)

* Fix test_delete_polling_removes_from_cache mock setup

- Mock async_delete_cache to properly execute the real implementation path
- Ensures init_async_client() is called and delete() is invoked on the returned client
- Fixes AssertionError: Expected 'delete' to be called once. Called 0 times.

* fix: resolve timeout in add_model_tab test by mocking useProviderFields hook

- Mock useProviderFields hook to prevent network calls and React Query delays
- Use waitFor to properly handle async operations
- Test now passes reliably without 10s timeout

* fix: add test timeout to prevent CI timeout failure

- Add 15 second timeout to 'should display Test Connect and Add Model buttons' test
- Test takes ~6 seconds locally, but CI was timing out at default 5 second limit
- Ensures test has sufficient time to complete in CI environment

* test: quarantine flaky test_oidc_circleci_with_azure

Quarantine test that fails with 401 Unauthorized from Azure OAuth.
The test is flaky and blocks CI builds. Marked with @pytest.mark.skip
until Azure authentication can be fixed or migrated to our own account.
