feat: events_list_event_tickets RPC for organizer ticket roster

Second nostr-transport handler on this branch. Returns paid + registered
counts plus the per-ticket roster (id, name, registered status, timestamp)
for one calendar event, organizer-only.

Backs the door scanner's counts strip and "scanned" list with backend
truth so a second organizer scanning on another device, an operator
switching from mobile to laptop mid-event, or a refresh in incognito
all see the same numbers instead of diverging from a per-device
localStorage cache.

Same authorisation posture as events_ticket_register: dispatcher
binds caller pubkey to wallet via AUTH_WALLET, handler verifies the
event's wallet is in the caller's wallet set. Only paid tickets land
in the response — proposed/unpaid rows are irrelevant at the door.

Webapp consumes this in aiolabs/webapp#73.
