feat: implement status automation and router pattern

- Implemented modular status automation system (statusHandlers.ts).
- Added handlers for 'Published' (Active/Qty 1), 'Sold' (Active/Qty 0), and 'Drafted'.
- Refactored onEdit triggers into a central Router pattern in OnEditHandler.ts.
- Updated Product.ts to support explicit quantity setting (fixed 0 value bug).
- Updated shopifyApi.ts to implement SetInventoryItemQuantity (using ignoreCompareQuantity).
- Consolidated triggers into single onEditHandler.
- Updated project documentation.
