BOLT-1268 — align event status display: rename Pending badge to Scheduled on Event Details

Trivial display alignment. Backend enum stays as pending; only the user-visible label on Event Details changes to Scheduled. List page filter dropdown already says Scheduled (events/page.tsx:94) so this just brings the Event Details badge into alignment. File: apps/dashboard/packs/programs/routes/(programs)/events/[id]/page.tsx around line 1043 — the Badge actions component renders {eventStatus === "active" ? "In Progress" : eventStatus} with className="capitalize". Need to map `pending` → `Scheduled` while keeping other status labels untouched. Do NOT touch the command-level status badges (events/[id]/page.tsx:917, :1304) — those map command statuses, not event statuses, and have their own `pending: "Pending"` label that should stay (commands genuinely are pending dispatch). Tests: snapshot/render test for the Event Details badge for each of draft/pending/active/completed. Branch: winston/bolt-1268-rename-pending-scheduled.
