Issue #48 — Backend: Mark Single Notification as Read

[yusuftomilola]

Location: backend/src/notifications/

Description

When a member opens or clicks a notification, it should be marked as read so the unread badge count decreases. This endpoint marks a single notification as read by its ID. The endpoint must verify that the notification belongs to the requesting user before updating it.

Acceptance Criteria

• PATCH /notifications/:id/read marks a single notification as read
  • Finds the notification by id — throws NotFoundException if it does not exist
  • Throws ForbiddenException if the notification does not belong to the requesting user
  • Sets isRead to true and saves the record
  • Returns { success: true, message: "Notification marked as read", data: Notification }
• Uses @GetCurrentUser('id') to identify the requesting user
• npx tsc --noEmit passes with no errors
