Arun: asylum numbers still rising

Quarter-end stock series to Dec 2025. A rise or fall is a net change in the number of people on support at period end, not the number of new claims or distinct people moving through the caseload. Support stock also overlaps with, but is not identical to, the awaiting-decision backlog.
