🛡️ Sentinel: [CRITICAL] Fix hardcoded secret bypass in Nginx config

[Snider]

🚨 Severity: CRITICAL
💡 Vulnerability: A hardcoded token xrpc-9f8e7d6c5b4a was embedded directly in the Nginx configuration file (wordpress.conf) to conditionally bypass the /xmlrpc.php block.
🎯 Impact: Exposes a hardcoded secret in version control, allowing a potential authentication bypass and brute-force/DDoS vector if discovered.
🔧 Fix: Replaced the conditional block with an unconditional deny all; for /xmlrpc.php and disabled logging.
✅ Verification: Verified Nginx syntax locally using nginx -t. No automated test suite exists.
📚 Journal: Documented the finding in .jules/sentinel.md as a critical learning.
