Connector for E-Commerce

This is a hidden technical module that other e-commerce connectors build on, so most of its effects appear inside sales orders, invoices, deliveries and payment modes rather than in a standalone menu.

On a sales order you get extra information and buttons: a flag showing the order was cancelled in the external shop, a "View Parent Sales Order" button when the order replaces an earlier one, and an "Ignore backend's cancellation, Keep Open" button (for sales managers) that opens a small window where you must write a reason. A search filter "Canceled in backend, to cancel" lists orders that were cancelled online and still need cancelling in Odoo.

Business rules: when an order is flagged as cancelled in the backend, Odoo posts a note on the order, its deliveries and invoices, tries to cancel the order automatically, and blocks confirmation through a sales exception until the cancellation is resolved. A parent order that still needs cancelling also blocks the child order.

Payment modes gain an "Import Rules" section (always, never, paid, authorized) and a number of days after which an unfulfilled order import is cancelled. Products gain a computed Tax Group, and price changes on products or variants trigger a notification event. Deliveries notify when a tracking number is added or when an outgoing shipment is done (partial or complete).
