fix(test): dismiss deletion-token modal without focus transfer

Clicking the ack button transferred focus out of the pad iframe, which
made subsequent keyboard-driven tests (Tab / Enter) silently miss the
editor. Swap the click for a page.evaluate() that hides the modal and
nulls clientVars.padDeletionToken directly, leaving focus where it was.
