product.pricelist.item: Extends name-based search so pricelist items can be found via pricelist, product, template, or category fields.
product.pricelist.item.duplicate.wizard: Duplicates selected fixed-price items with new start/end dates, applies a variation percentage to the fixed price, and ends the prior item just before the new start.
sales: Adds a Pricelist Items menu with an editable list view, a variation percent column, and filters for current, global, category, and product-specific rules.
