This PR implements defense-in-depth security best practices by adding standard HTTP security response headers to the api_v2 service. These headers mitigate several classes of common web vulnerabilities. Headers added: - Content-Security-Policy (default-src 'none'; frame-ancestors 'none'; sandbox): Disables loading/executing external assets as it's an API, preventing XSS and framing. - Strict-Transport-Security (max-age=63072000; includeSubDomains; preload): Enforces HTTPS connection for 2 years. - X-Frame-Options (DENY): Prevents clickjacking by disabling framing. - X-Content-Type-Options (nosniff): Prevents MIME-type sniffing. - Referrer-Policy (no-referrer): Prevents leaking referring URLs in request headers.

🛡️ Sentinel: [security improvement] Add security headers to API
Severity: MEDIUM
Vulnerability: Missing HTTP security headers. Without these, the application lacks a secondary layer of defense against attacks like MIME-sniffing, clickjacking, and man-in-the-middle downgrade attacks.
Impact: While primarily an API backend, missing these standard headers fails to follow best-practice defense-in-depth principles. For example, if a client accidentally treats a JSON response as HTML, lack of CSP and X-Content-Type-Options could lead to XSS.
Fix: Injected 5 standard security headers into the
api_v2Axum routing layer usingtower-http::set_header::SetResponseHeaderLayer.Verification: The headers are correctly implemented and compilation passes. The test suites for both frontend and backend continue to pass successfully.
