Subject: [PATCH] feat: GET /tickets/event/{event_id}/stats for door-scanner
 roster
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Mirrors the events_list_event_tickets nostr-transport RPC for callers
that don't hold a raw user prvkey (the webapp post-#9, in particular —
useTicketScanner.refreshStats now has a working HTTP path). Auth:
wallet admin_key + the event's wallet must be in the caller's wallet
set, matching the register endpoint's owner check.

Without this endpoint the activities scanner page loaded its initial
counts (via no-op fallbacks) but every post-scan refreshStats returned
404, leaving the Scanned counter stuck at 0 even though registrations
landed correctly. Surfaced by aio-demo manual test on 2026-06-03.
