[ADD] new_product_type_kit: completed kit product type with wizard & sub-product
- Introduced 'Is Kit' field on product templates to define kit-type products - Added Many2many field to select sub-products for a kit - Added smart button 'Configure Kit' on sale order line, visible only for kit products - Created a wizard to select sub-product quantity and price per main product - Sub-products are auto-added as separate sale order lines under the main kit line - Sub-product lines are read-only & priced at 0 (cost included in main product) - Sub-products support storable/consumable product types for stock tracking - Main product's unit price remains unchanged; subtotal includes sub-product costs - Sub-product lines are auto-deleted if the main kit line is removed - Added 'Print in Report' checkbox on Sale Order to control sub-product visibility - Applied conditional display of sub-products in: - Sale Order PDF - Portal Order Preview - Invoice PDF (QWeb-safe logic using t-set variables)
