Standardize judgels-client test patterns

- Replace document.querySelector with testing-library selectors (getByRole,
  getByLabelText) for form inputs, selects, checkboxes
- Add aria-label to FormTable components for accessibility and testability
- Add role="article" to announcement/clarification cards, use role="link"
  for problem cards
- Replace document.querySelectorAll CSS class selectors with getAllByRole
- Improve table assertions to check cell content matrix instead of just
  getByText/row count
- Add missing nock.isDone() checks in ContestEditGeneralTab,
  ContestEditConfigsTab, and ContestEditDescriptionTab tests
