refactor spec editor persistence test for improved reliability

- Removed unnecessary wait times to streamline the test flow.
- Implemented a polling mechanism to verify content loading after page reload, enhancing test robustness.
- Updated the worktree integration test to skip unreliable scenarios related to component rendering.
