Add sudo() to pricelist_item and fiscal position fallback in _get_pricing_info
so portal users can price the delivery product without triggering an AccessError
on account.tax. Remove the redundant #home-delivery-btn click handler from
website_sale.js — home_delivery.js already owns that button via
bindShopHomeDeliveryButton(), which manages the active class and localStorage cart.
