Add ability to unassign a donation from a registration

Assigning a donation to a registration was one-way: the refund flow
could reverse the money but left the donation's "leg" payment in
place, permanently locking that portion of the donation as used even
though it had been refunded back out. Adds POST
/api/payments/unassign-donation, which deletes the leg, reverts the
registration's status/tickets the same way a refund downgrade already
does, and notifies the registrant. New "Assigned donations" list on
the supervisor Payments page surfaces existing legs with an Unassign
action, since no such list existed before.

## [Unreleased]
### Added
- Supervisors can now unassign a donation that was previously applied to a registration, from a new "Assigned donations" list on the Payments page. This reverses the allocation (the registration's balance goes back up and the donation becomes available again), reverting the registration's status and revoking any tickets issued only because that allocation completed payment — blocked if a ticket has already been scanned. The registrant is notified by email/WhatsApp, mirroring the notification sent when a donation is first applied.
### Performance
- Reconciling a Yoco card payment or sending a payment link on the supervisor Payments page no longer blocks the response on ticket-PDF generation and email/WhatsApp sends — these now run in the background, matching how manual payments already worked.
