/* Scheduled events become one system: an event has a name, a mode (0 off, 1 on by its schedule, 2 always on), a
   schedule (recurring rules as JSON, see dCommon/ScheduleRules.h; empty: once, from starts_at to ends_at), a priority
   and parts that switch on and off together (JSON [{kind, config, applied, state, status}], see
   dDashboardServer/routes/EventParts.h): a feature flag, vanity changes, a live event, announcements, a restart.
   The old columns feature, slot, previous_value and previous_web_wins are no longer read: each calendar event becomes
   an event with one feature part holding them. Each vanity event becomes an event with one vanity part; the
   vanity_events table is no longer read either (kept, so nothing is lost). */
