test: replace hardcoded delay() calls with retrying assertions

- Remove comfyPage.delay(1000) in toggle test — the preceding
  toHaveScreenshot already confirms the canvas is stable
- Replace comfyPage.delay(300) in two dialog-dismiss tests with
  toPass() blocks that retry the click+hidden assertion, handling
  the case where the click-outside handler isn't attached yet
