feat(shared): add error handling & structured logging strategy

- Global exception filter with consistent error response format
- Domain exceptions (NotFoundException, ValidationException, etc.)
- Error codes enum for domain-specific error identification
- Correlation ID middleware for request tracing
- Request/response logging middleware with structured JSON
- PII masking in logs (emails, phone numbers, sensitive fields)
- Enhanced LoggerService with pino formatters and ISO timestamps
- Tests for exception filter, domain exceptions, and PII masker
