This commit finalizes Phase 4 of the Event & Session Overhaul:
1. Implements session pause logic across PostgreSQL schema, Valkey cache, and `auth_forward.ts` edge check (`is_paused`).
2. Implements non-destructive operational endpoints (`/api/events/:id/rotate-pin`, `/api/events/:id/expand`, `/api/events/:id/attendees`) with Zero-Trust Ownership verification.
3. Upgrades existing `end` and `extend` endpoints in `events.ts` to utilize robust Zero-Trust Ownership queries (created_by OR isGlobalAdmin).
4. Creates `EventAttendeesDrawer.tsx` to handle live participant inspection and individual session controls (Pause, Revoke).
5. Updates `EventCockpitDeck.tsx` and `SessionsScript.tsx` to mount and drive the new controls via vanilla JavaScript, respecting zero-framework guidelines.
6. Ensures `deno fmt`, `deno task lint`, `deno task check` and `deno test` execute successfully against the new schema and API guards.
