Fail CI if a query is missing a mock

[radoslaw-szpiech]

The Chore

Add check for missing query mocks and fail before e2e test run

Tasks

• [ ] Add some kind of linting or code analysis tool to detect if queries are missing mocks for tests
• [ ] Add a github action to fail if missing mocks are found
• [ ] Ensure the action runs before the e2e test run so we can fail early
