fix(mobile): add missing accessibilityLabels across all screens

- settings.tsx: labels on sign-out, feedback type chips, submit button
- capture.tsx: labels on workspace selection chips
- index.tsx: labels on workspace filter chips, note card pressables
- search.tsx: labels on search input, result row pressables
- note/[id].tsx: labels on edit, save, cancel buttons
