Configure Security Headers Csp
Configures HTTP response security headers and a strict, nonce/hash-based Content-Security-Policy — script-src with a per-request nonce or sha256 hash plus 'strict-dynamic' (so you can drop host allowlists and 'unsafe-inline'), object-src 'none', base-uri 'none', frame-ancestors to control framing, a Report-Only rollout via report-to/report-uri before enforcing, plus HSTS with includeSubDomains+preload, X-Content-Type-Options: nosniff, Referrer-Policy, a deny-by-default Permissions-Policy, correct CORS (echo a single allowed origin, never wildcard '*' together with Access-Control-Allow-Credentials), and cookie flags Secure+HttpOnly+SameSite. Eliminates inline-script XSS sinks, clickjacking, MIME-sniffing, mixed content, and credentialed-CORS leaks by policy rather than per-bug patching.
