auto-claude: subtask-4-2 - Update routes_page.dart to use new dialog components

- Replaced inline loading dialogs with LoadingDialog component
- Replaced inline notes dialog with NotesDialog component
- Replaced inline photo confirmation dialog with PhotoCaptureDialog component
- Added missing localization strings for completingDelivery, markingAsUncompleted, and deliveryMarkedUncompleted
- Fixed BuildContext usage across async gaps by capturing l10n early
- Fixed unused result warnings by using ref.invalidate instead of ref.refresh
- Removed unnecessary non-null assertions
