fix(lint,test): unblock CI on chore/fc-10-explore-sqllab-misc

Two failures from the latest commits on this branch:

1. oxlint no-use-before-define on DatasourceEditor.tsx — the
   isEditModeRef / onQueryFormatRef declarations sat after the
   componentDidMount useEffect that closes over them. JavaScript closes
   over the names at call time so it ran fine, but oxlint reads top-down
   and flags the order. Move the ref declarations and their sync useEffect
   ahead of the componentDidMount effect; lint clean and behavior
   identical.

2. CopyToClipboard.test.tsx used userEvent.keyboard('{enter}'), an API
   added in @testing-library/user-event v13.4. The pinned version in this
   repo is v12.8.3, so the call resolves to undefined and the test
   crashes with TypeError. Switch to fireEvent.keyDown(button, {key:
   'Enter'}), which is v12-compatible and directly exercises the
   component's onKeyDown handler we're testing.
