Merge feat/inventory-mobile-surface into main (Stage 6C complete)

- Add MobileInventoryPage with search bar, horizontal status filter chips
  (All / In Stock / Low Stock / Out of Stock / Draft), item count display,
  compact _MobileInventoryCard list at 120px height (name, SKU, status chip,
  quantity-on-hand), pull-to-refresh, and _detailPageActive guard to suppress
  behind-route SnackBars
- Add MobileInventoryDetailPage wrapping shared InventoryDetailPanel; local
  controller listener for SnackBar feedback; showAdjustQuantityDialog on
  Adjust Quantity tap; haptic feedback (mediumImpact on result, lightImpact
  on successful adjust); SafeArea wrapper
- Update MobileShell Inventory tab (case 1) from shared InventoryPage to
  MobileInventoryPage; remove unused feature_inventory direct import
- Add 6 Stage 6C widget tests: Inventory tab search bar, status filter chips,
  item count, card navigation to detail, adjust quantity dialog, back
  navigation returning to list (26/26 kell_mobile total)

All tests passing: 26/26 kell_mobile, 75/75 feature_inventory
dart analyze --fatal-infos: no issues found
Stage 6 complete — Products, Orders, and Inventory all have mobile surfaces
