//! Comprehensive security tests for HTTP handlers.
//!
//! These tests verify protection against common security vulnerabilities:
//! - Injection attacks (SQL, XSS, command injection)
//! - Path traversal attacks
//! - Authentication bypass attempts
//! - Authorization checks
//! - Template injection
//! - Input validation
