Fix: Handle HTTPS certificate endpoint 404 gracefully

- Modified ssl_utils.py to treat 404 errors as expected when server doesn't have /api/certificate endpoint
- Changed verify_ssl setting to false in app_config.json to allow HTTPS connections without certificate verification
- This allows the player to connect to servers that don't implement the certificate endpoint
