Subject: [PATCH] [ADD] new_product_type: add configurable kit product support

Standard Odoo requires the Manufacturing (MRP) and Bill of Materials (BoM)
modules to handle kit products. Users who only do trading or pure sales
without manufacturing need a lightweight way to sell product bundles,
manage their pricing dynamically, and control their visibility on invoices
without overhead.

WHAT:
- Added a new product type for kits without MRP dependencies.
- Created a configuration wizard on sale order lines to manage kit items,
quantities, and pricing before confirmation.
- Implemented parent-child relations between sale order lines to link kits with
sub-products.
- Made sub-product lines readonly and protected them from direct deletion to
ensure data integrity.
- Updated report logic (sale orders, portal, invoices) with a dedicated print
option to show or hide sub-products.
