- Save and restore dialog open/closed state in sessionStorage (App.jsx)
- Persist form data: locator, error, busy, jobStatus, jobUid (CaptureDialog.jsx)
- Auto-resume polling if capture job was in progress before page refresh
- Only clear form on fresh user click, not when restoring from refresh
- Clean up sessionStorage when capture completes successfully
Fixes: Capture pop-up disappears on page refresh with unsaved data
