Merge chore/dart-analyze-cleanup into main (analyze clean)

Remove 6 redundant direct src/ imports from feature_orders test files.
All symbols are already re-exported via the package barrel
(feature_orders/feature_orders.dart), making the src/ imports unnecessary.

Files cleaned:

- test/orders_controller_test.dart — removed orders_controller.dart import
- test/widgets/order_card_test.dart — removed order_card.dart import
- test/widgets/order_detail_panel_test.dart — removed order_detail_panel.dart import
- test/widgets/order_status_chip_test.dart — removed order_status_chip.dart import
- test/widgets/orders_page_test.dart — removed add_note_dialog.dart and
  order_detail_panel.dart imports

All 115/115 feature_orders tests still passing.
dart analyze: no issues found across all packages.
