Support unread count + per-row hint (Wave 72)
- Migration 0069 — `support_tickets.last_seen_by_customer_at` + partial unread index. Bumped on every authed `GET /widgets/:id/my-tickets/:ticketId`.
- New `GET /widgets/:widgetId/my-tickets/unread-count` Bearer-JWT endpoint returns `{ count: number }`. 5s threshold defeats the instant +1 right after a ticket is created by the submitter.
- Ticket list endpoint now returns `unread: boolean` per row. Worker `/embed/tickets` shows a blue dot on unread rows.
