feat(events): pipe displayTimezone through list and sidebar formatters

Sidebar (EventsMiniSidebar), public events list, member dashboard
"Upcoming" block, and EventTicketPurchase all formatted dates in
viewer-local TZ. Switch each formatter to accept the event (or an
eventTimezone prop) and pass it to Intl.DateTimeFormat so the
displayed wall-clock matches the event's intended zone.
