Push Notification Backend Infrastructure

Push Notification Backend Infrastructure

What & Why

Add the server-side foundation for Web Push notifications. The platform currently only has in-app notifications (polled every 30s) and email reminders. Real-time push notifications will let parents, coaches, and admins get instant browser alerts for important events — new messages, schedule changes, payment reminders, etc.

Done looks like

• A table stores browser push subscription data per user
• VAPID keys are generated and stored as environment secrets
• API endpoints exist for subscribing, unsubscribing, and checking push status
• A reusable utility can deliver push messages to all of a user's devices
• Expired/invalid subscriptions are automatically cleaned up on delivery failure (410 Gone)
• Push notification preferences (per-category opt-in) are stored per user

Out of scope

• Frontend UI for managing push preferences (Task #66)
• Service worker push event handling (Task #66)
• Actually wiring push into existing notification triggers (Task #67)
