test: improve test quality based on code review feedback

- basic-form: actually click submit button and verify fakeSubmitForm
  was called, instead of just asserting button exists
- basic-form: import waitFor from @testing-library/react
- analysis: assert '0 items' text after empty data loads instead of
  checking element that exists on initial render
- Replace dynamic import with static import in 3 test files where mock
  factories don't reference file-level variables (analysis, basic-form,
  table-list); keep dynamic import in app.test.tsx where mock factory
  references mockHistory/mockQueryCurrentUser which aren't available
  during hoisted static import resolution
