📌 Issue Title / Suggestion Summary

[GSSoC'25] Feature: Add Real-Time Notification Alerts for Pending Payments

📝 Detailed Description

Currently, users don’t receive real-time alerts when an expense is added or settled within a group. Adding in-app notification alerts will improve the experience by helping users stay updated with group activity.

It will enhance coordination among group members and reduce confusion about who paid and when.

🛠️ Proposed Solution / Steps to Reproduce

1. Use React Native's notification support (e.g., Notifee or FCM).
2. Trigger notifications when:
   • A new expense is created
   • A payment is marked as settled
3. Show the notification inside the app (possibly via toast/snackbar).
4. Optional: Add a toggle in app settings to mute/unmute notifications.

@muskanyadav1234 good observation. You could work on the notification service.

Please submit the proposed architecture of the notification service in the backend [sequence diagram] such that further discussions can be conducted

Thank you @devasv23 for the guidance!

I'll start working on the architecture of the Notification Service.
I'll share a detailed sequence diagram soon for discussion and feedback.

Please let me know if there are any specific requirements or constraints to keep in mind.
