Win-back now reaches portal cancellations that skipped a cancellation flow

A customer could cancel through the portal without ever going through a merchant-built cancellation flow: a shop with no flow set up, an emailed pause/cancel link, an empty-body cancel, or Subi's own default flow. Until now, those cancellations didn't enter a shop's win-back campaign aimed at every cancellation, even when one was active.

Those portal cancellations now enrol in the shop's active win-back campaign the same as any other cancellation, and the customer receives its emails going forward.

This applies to cancellations from today onward; it doesn't reach back to re-enrol customers who already cancelled this way.
