invoices: cancel with stamped PDF, superuser-only hiding

An invoice issued by mistake could only be left pending or marked paid.
Add cancel (with an optional reason) and reinstate. Cancelling renders a
third PDF variant with a diagonal CANCELLED stamp and the date/reason,
and it becomes the current one, so the client's link and download show
the invoice as void. Cancelled wins over paid in the status, and marking
a cancelled invoice paid is refused.

Superusers can also hide an invoice: it disappears from the admin list,
dashboard and invoice pages for every other user, while the client's
public link keeps working.
