Fix X-Powered-By header leak on bypassed endpoints

[shenald-dev]

Disables the X-Powered-By header explicitly at the application level in src/index.js using app.disable('x-powered-by'). This addresses an issue where the /health endpoint, which intentionally bypassed helmet() for performance reasons, was leaking the framework identity. This change also eliminates the minor CPU overhead of allocating and setting the header only for it to be stripped later by downstream middlewares. Added a regression test to ensure /health no longer returns the header.
