perf(health): optimize health check endpoint placement

[shenald-dev]

Moved the /health endpoint definition above helmet() and cors() in src/index.js to bypass their unnecessary CPU and latency overhead for simple load-balancer pings, drastically increasing throughput. Manually added the Content-Type header to the health response to ensure correct behavior.

The change looks good for performance. Consider adding a brief comment above the health route explaining why it's placed before helmet() and cors() middleware, and optionally add a simple test to verify the endpoint returns the expected Content-Type and status code.

Reviewed — quality: high
