Stock Request Cancel Confirm

This module makes cancelling a stock request or a stock request order a two-step action. When a user presses the cancel button on a stock.request or stock.request.order, Odoo no longer cancels it immediately: a confirmation wizard opens first, where the user can enter a reason for cancelling. The reason is optional, so the cancellation can still go ahead without typing anything.

• The confirmation applies to both individual stock requests and stock request orders.
• The reason field is optional, not mandatory.
• If the user confirms, the normal cancellation runs and the reason is stored with the record.
• If the user puts the record back to draft with the reset-to-draft action, the previously entered cancellation confirmation data is cleared, so an old reason does not stay attached to the record.
• A technical bypass exists so that cancellations triggered automatically by other processes do not show the wizard.

No new menus or screens are added; the change appears directly on the existing stock request and stock request order forms, through the cancel and reset-to-draft buttons. The module touches the stock.request and stock.request.order models and relies on the shared cancellation-confirmation behaviour provided by the base cancellation confirmation module.
