fix(tests): improve Astrolabe integration test reliability

- Replace Close button click with Escape key in app password dialog
  (h2 element was intercepting pointer events)
- Make test_users_setup fixture idempotent by checking user existence
  before creation and only tracking created users for cleanup
- Fix search results detection by removing wait for .app-content-wrapper
  CSS class that doesn't exist in Astrolabe's Vue app
- Add progress logging during results polling
- Increase polling timeout to 30 seconds for search results
