Fix nested modifier saving with proper parent tracking

- Fixed _addModifiersRecursively to track OrderLineItemID through recursion
- Changed from hardcoded parentOrderLineItemId: 0 to actual parent IDs
- Added logic to find root item's OrderLineItemID before starting recursion
- Added logic to find each modifier's OrderLineItemID for its children
- Fixed API_BASE_URL to AALISTS_API_BASE_URL for environment consistency
- Added comprehensive debug logging for troubleshooting

This fix ensures nested modifiers (e.g., Customize Spread > Extra) are
properly saved to the database with correct parent-child relationships.
