Implement comprehensive logging with structured format and correlation IDs

[Smartdevs17]

Description

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

Acceptance Criteria

• Structured JSON logging format
• Correlation ID propagation across async boundaries
• Log level configuration per module
• PII redaction in log output
• Centralized log aggregation
• Log query performance optimization

Technical Scope

• api/src/middleware/logger.ts
• oracle/src/
• api/src/middleware/requestId.js
• Edge: async context propagation, log volume management, sensitive field detection
