[Enhancement] Expose Prometheus-compatible metrics across all services

[vraj826]

📄 Description

MicroForge emphasizes monitoring and observability, but currently lacks a standardized metrics exposure mechanism.
This issue proposes adding /metrics endpoints (Prometheus format) to all backend services to expose CPU, memory, request count, and latency metrics.

✅ Scope

• Add metrics middleware per service
• Ensure consistent metric naming
• Update README with metrics access info

🎯 Outcome

• Enables Prometheus / Grafana integration
• Aligns with production-grade observability
