Fix: Allow public access to Swagger UI and OpenAPI endpoints

Added explicit HTTP auth permissions to allow unauthenticated access to:
- /q/* (health endpoints)
- /openapi (OpenAPI spec)
- /swagger-ui/* (Swagger UI)

This fixes the issue where proactive auth mode blocked access to
documentation endpoints in production.
