fix: address review feedback on auto-save

- Snapshot fields at start of performSave to avoid race with user edits
  during async save (fields could change between await and lastSaved update)
- Only update lastSaved tracking on successful save, so failed saves
  are retried on the next debounce cycle
- Stop restoring title after Untitled fallback in autoSave(), which was
  re-triggering the auto-save effect
- Capture note count before opening editor in empty-note e2e test
