Description
This PR adds HTTP security headers to the application using the
helmetmiddleware, significantly improving the app's security posture. A Content Security Policy (CSP) is configured to allow existing third-party resources (Google Fonts, Razorpay checkout, CDNjs, Vercel analytics) while blocking common attack vectors like XSS, clickjacking, and MIME sniffing. Also refactors an inline event handler for CSP compliance.Fixes #45
