P0-S1-003: Deploy Observability Stack

[Reg-Kris]

User Story

As an operations team member, I need monitoring and logging so I can troubleshoot issues and monitor system health.

Current State

• Observability stack is offline
• No centralized logging or metrics collection
• Service health monitoring not functional

Acceptance Criteria

• Prometheus metrics collection for all 8 services
• Grafana dashboards showing service health and performance
• Loki log aggregation collecting logs from all services
• Jaeger distributed tracing for request flow visualization
• Health check endpoints implemented for all services
• Alert rules configured for critical failures

Branch Name

feat/observability-stack

Story Points

10 (Medium-high complexity with multiple monitoring tools)

Dependencies

• All services must be running and accessible
• Docker compose configuration access
