feat(standups): add starting soon notifications

[idoshamun]

Summary

• add a new live-room starting-soon notification type and copy
• schedule immutable standup reminders hourly via a delayed Temporal workflow
• send the reminder through the normal notification pipeline at due time so push and realtime behavior stay aligned

Validation

• pnpm exec eslint src/cron/liveRoomStartingSoonNotifications.ts src/workers/liveRoomNotifications.ts src/workers/notifications/liveRoomStartingSoonNotification.ts src/workers/notifications/index.ts tests/cron/liveRoomStartingSoonNotifications.ts tests/workers/notifications/liveRoomStartingSoonNotification.ts .infra/crons.ts --no-ignore
• pnpm run build
• Jest is currently blocked in this checkout by the preexisting test cleanup error: relation "spotlight_action" does not exist from tests/setup.ts before the target suites execute.

🍹 The Update (preview) for dailydotdev/api/prod (at 5576781) was successful.

✨ Neo Explanation

Routine feature deployment adding "live room starting soon" push/in-app notifications via a new Temporal-scheduled workflow and PubSub subscription. ✅ Low Risk.

This PR introduces a "live room starting soon" notification feature. When a scheduled live room is created, a Temporal workflow is registered (5 minutes before the scheduled start) that triggers a new live_room_starting_soon in-app notification to all room subscribers. The new PubSub subscription (api.live-room-starting-soon-notification) wires the delayed notification reminder topic to the new worker that processes these notifications.

The Kubernetes deployment and cron updates are routine image tag bumps to the new commit SHA. The migration jobs cycle as expected for a new deployment.

🔵 Info — The new PubSub subscription reuses the existing api.v1.delayed-notification-reminder topic (shared with poll result notifications). The worker correctly filters by entityTableName to avoid processing unrelated entities, so there is no cross-contamination risk, but this is worth noting for observability — a misconfigured Temporal workflow firing against a non-live-room entity will be silently dropped.
