Notification API: In-app delivery only (no push/badge)

Problem

Notifications sent via /api/v1/notifications/send only show up in the in-app notification center. They don't trigger push notifications, lock screen alerts, or badge indicators.

This means users have no idea they received a notification unless they manually open the notifications panel.

What happens now

API notifications:

• Show in notification center ✓
• Push to lock screen ✗
• Badge on notification icon ✗

On-chain notifications (token transfers, etc.):

• Show in notification center ✓
• Push to lock screen ✓
• Badge on notification icon ✓

Why this matters

We tested with multiple users - none of them noticed the notifications until we told them to check. They just don't see them.

This defeats the purpose of notifications. Users need to be alerted about time-sensitive things like rewards expiring, events ending, or getting outbid. Right now the notification API is basically useless for user retention.

Suggested fix

Make API notifications behave the same as on-chain notifications - deliver them as actual push notifications that users will see.
