Collect a Google Pay shipping address and option on web - #1006

Google Pay on web builds no shipping fields and hardcodes callbackIntents to PAYMENT_AUTHORIZATION, so a merchant cannot collect a shipping address, offer shipping options, or recalculate the total while the sheet is open. Add shippingAddress and shippingOptions to the button config, derive callbackIntents from that config, and wire onPaymentDataChanged to merchant onShippingAddressChange / onShippingOptionChange callbacks. The sheet can raise several data changes in one session, so each request carries an id and the frame resolves only the reply that matches it.

Google Pay on web did not expose shipping fields and hardcoded
callbackIntentsto["PAYMENT_AUTHORIZATION"]. Merchants could not collect a shipping address, offer shipping options, or update an open payment sheet.This adds
shippingAddressandshippingOptionsto the button configuration. Shipping options also enable address collection. Address and option callbacks receive the current shipping state and can return a synchronous or asynchronous partial update for the total, line items, or available options. A callback can instead return a typed Google Pay error.Callbacks have a 10-second timeout. The SDK validates option IDs and defaults, correlates concurrent iframe replies, preserves partial updates within one sheet session, and resets them before the next session.
