Several storefronts share one gateway — the city booking sites and the
ClinicPro panel itself — so the payments report could not say where a
transaction originated. The payment already stores the return address it was
started with; the domain is derived from it.
Lowercased and stripped of "www." so one domain is one value in the report,
null when a payment has no return address. Exposed on both the list and the
detail (which also carries the full address), and the list search now matches
it, so filtering to a single site needs no new parameter.
