[BE-31] Add structured request logging middleware with correlation IDs in opsce module

[yusuftomilola]

Problem

The backend has no request logging. When errors occur in production, there is no way to trace a request through the system or correlate incoming requests with outgoing responses in logs.

Proposed Solution

Create backend/src/opsce/common/middleware/logger.middleware.ts. Generate a UUID correlationId per request, attach it to request and response headers, and log structured JSON per request/response.

Acceptance Criteria

• Each request gets a X-Correlation-Id UUID header (generated if not provided by the client)
• Logs incoming request: method, URL, correlationId, userAgent, IP
• Logs outgoing response: statusCode, duration in ms, correlationId
• Sensitive headers (Authorization, Cookie) are redacted from logs
• Middleware applied globally in OpsceModule
• Log output is structured JSON for log aggregation compatibility
