feat: use propose endpoint for user event creation

Replace CreateActivityDialog (direct Nostr publish) with
CreateEventDialog (LNbits propose flow) on ActivitiesPage.
Users submit events via POST /events/propose with invoice key.
Admin reviews and approves before events go live.

Add proposeEvent() to TicketApiService for invoice-key auth.
