"Copy" on each event card opens the event editor filled in from that
event (campus, sessions, options, variants, early birds, sections, form,
recipients, feedback questions, certificates, reminders). "New start"
moves every date with it. Allocation groups and, for admins, planned
costs are copied by POST /api/events/:id/copy-from. Registrations,
coupons, attachments, kids check-in and volunteer roles are not copied.
Roadmap: event series and cloning ships as 1.47.0-1.47.3.
