[FIX] product_sale_price_from_pricelist: Fix JavaScript error in product form view

Fixed TypeError: value.toFixed is not a function when rendering monetary
fields in product form views. Added default=0.0 to list_price_theoritical
and last_purchase_price_received fields to prevent JavaScript from trying
to format False values as numbers.

Version bump: 18.0.2.1.0 -> 18.0.2.2.0
