Security vulnerabilities and automated fixes for access control issues

A critical security vulnerability in `routes.js` exposed a `/test` endpoint in production without any authentication or authorization checks, potentially allowing attackers to gather system information and reconnaissance data. The fix restricts this debugging endpoint to non-production environments only, preventing unauthorized access while preserving development functionality.
A critical authentication bypass in the `/api/posts` endpoint allowed any unauthenticated user to create, update, or delete posts without verification. The POST endpoint had zero authentication checks, while PUT and DELETE endpoints used a trivially bypassable username comparison that attackers could forge by simply including the target username in their request body. The fix validates user identity by looking up the userId in the database before any post operations.
A critical authorization bypass was discovered in lib/router.js where readOnly and noDelete configuration options were only enforced through UI controls, not server-side middleware. Any authenticated user could bypass these restrictions by sending direct HTTP requests to perform destructive operations like database deletion or document modification. The fix adds Express middleware that enforces these security modes at the server level, blocking POST, PUT, and DELETE requests when appropriate.
CVE-2025-22235 is a high-severity vulnerability in Spring Boot where `EndpointRequest.to()` creates an incorrect request matcher when an actuator endpoint is not exposed, potentially allowing unauthorized access to protected endpoints. The fix upgrades Spring Boot from 3.4.4 to 3.4.5 in the anti-corruption-layer service's `pom.xml`. This is particularly dangerous because actuator endpoints can expose sensitive operational data and administrative functions.
