🛡️ Sentinel: [CRITICAL] Fix hardcoded XML-RPC bypass token

[Snider]

🚨 Severity: CRITICAL
💡 Vulnerability: A hardcoded token xrpc-9f8e7d6c5b4a was present in server-php/config/conf.d/wordpress.conf allowing a bypass to the otherwise blocked XML-RPC endpoint.
🎯 Impact: Anyone with knowledge of this configuration parameter could bypass the intended block and access the potentially vulnerable /xmlrpc.php endpoint.
🔧 Fix: Removed the conditional token check and replaced the configuration with a strict, unconditional deny all; directive for the /xmlrpc.php location. Also created .jules/sentinel.md with a journal entry noting the vulnerability and how to prevent it.
✅ Verification: Verified using grep that the token no longer exists in the codebase. Docker build verifies local integration, ignoring local overlay filesystem limitations.
