Add real-time dashboard metrics feed over WebSockets

[nanaf6203-bit]

Context

Dashboard/analytics compute on request (REST), and the platform already has Socket.IO + Redis presence infrastructure (notifications.gateway.ts).

Problem

Admins and agents refresh manually; there's no push channel for 'new transaction / fraud alert / queue depth'. The realtime infra exists but is used only for per-user notifications.

Proposed approach

Add an analytics Socket.IO namespace pushing low-frequency aggregate snapshots (queue depth via admin queue service, fraud alert counts, property/transaction deltas) with a heartbeat, using the existing Redis adapter for multi-replica.

Acceptance criteria

• Realtime feed updates ≤10s after events; no pressure on DB (cached).

I’d like to take this issue. I’ll extend the existing Socket.IO/Redis infrastructure with an analytics namespace that pushes cached, low-frequency snapshots for queue depth, fraud alerts, and transaction/property changes, including heartbeat support for multi-replica deployments. I’ll ensure updates stay within the ≤10s target without adding unnecessary database pressure and add coverage for the realtime flow. I can deliver a focused, tested PR promptly.
