Subject: [PATCH] [IMP]  new_product_type : Implemented custom Kit/Bundle
 product functionality:

- Product-level kit configuration
- Sale order wizard for component adjustment
- Parent-child linking of kit lines
- Optional breakdown visibility in reports
- Prevent users from deleting kit sub-products directly
- Automatically delete all child lines when parent kit line is removed
- Load price from extra_price instead of price_unit
