Subject: [PATCH] [ADD] product_type_kit: kit product added with sub product
 selection wizards

Implemented 'Is Kit' boolean field on product form to enable kit functionality
Added many2many field to link subproducts with main kit product
Implemented conditional visibility for subproduct when 'Is Kit' is enabled
Enabled button on sale order line to configure subproducts via wizard
Main product price auto-calculates from subproduct total
Implemented checkbox to control visibility of subproducts in print reports
Ensured deletion of main product also removes all related subproduct lines
