auto-claude: subtask-2-2 - Create NotesDialog component for displaying delivery notes

- Add reusable NotesDialog component that extracts and displays notes from delivery orders
- Add static show() method for convenient dialog display with empty notes handling
- Add localization strings for notes dialog (EN/FR): notesTitle, noNotesMessage, close
- Follow existing dialog pattern from NavigationTermsAndConditionsDialog
