- Added a button in SwipeableInventoryTile to move items to pantry with appropriate error handling.
- Introduced movePantryItemToInventory method in PantryRepository to support moving items back to inventory.
- Refactored PantryScreen to rename _addToInventory to _moveToInventory for clarity and updated UI to reflect changes.
