Fixes #30169

Summary

What

This PR introduces structured logging support (JSON format) to the backend service. It standardizes log outputs, making them machine-readable and consistent.

Why

To better integrate with modern log aggregation and observability systems (e.g., ELK, Datadog, Loki). Structured logging eliminates the need for complex regex parsing and improves query capabilities on log fields.

Key Changes

  • Refactored logging implementation to support JSON serialization.
  • Unified log field naming (e.g., level, msg, ts, trace_id).
  • Added configuration to toggle between console (text) and json formats (defaulting to text for dev environments).

Fixes #30169
