Subject: [PATCH] [ADD] add_pricelist_price: add book price to sale and invoice
 lines

Implemented a new module to compute and display the 'Book Price' (pricelist price)
on Sale Order and Account Move lines for comparison with the actual unit price.

Changes:
- Models: Added `book_price` computed field to `sale.order.line` to fetch price from the order's pricelist.
- Models: Added `book_price` computed field to `account.move.line` with fallback logic for related sale orders or partner pricelists.
- Views: Extended Sale Order form to display `book_price` after quantity.
- Views: Extended Invoice form to display `book_price` before unit price (for customer invoices only).
