Add structured logging with correlation IDs and centralized aggregation

[Smartdevs17]

Description

Logs are unstructured making debugging across services difficult. Implement structured logging with correlation IDs.

Acceptance Criteria

• Structured JSON logging format
• Correlation ID propagation across async boundaries
• Log level configuration per module
• PII redation in logs
• Centralized log aggregation (ELK or Loki)
• Log query dashboard with filtering

Technical Scope

• backend/services/logging.ts
• src/services/
• Edge: async context propagation, log volume management, sensitive field detection

@uboho-prog has applied to work on this issue as part of the Stellar Wave Program's 5th wave.

I’d like to work on this by introducing a structured logging system that outputs consistent JSON logs enriched with correlation IDs across all async flows. I will ensure IDs propagate safely between services, add per-module log level controls, and implement PII redaction to prevent sensitive data leaks. I will also wire logs into a centralized aggregation pipeline (ELK or Loki) and support a queryable dashboard for filtering and debugging across services.
