🛡️ Sentinel: [CRITICAL] Fix missing authentication on sources endpoint

[parvezk]

🚨 Severity: CRITICAL
💡 Vulnerability: The endpoint /api/jules/sources/route.ts was missing an authentication check. This endpoint makes an external API call using a server-side API key, completely bypassing Supabase Row Level Security (RLS). This allowed any unauthenticated user to trigger external API calls and view connected sources using the server's key.
🎯 Impact: Unauthenticated users could enumerate connected Jules sources and abuse the server-side API key limits by making unauthorized requests.
🔧 Fix: Added currentUserId() check to the top of the route handler, returning a 401 Unauthorized error if no user ID is present.
✅ Verification: Verified the route successfully fails securely when currentUserId() returns null by verifying the tests and building the app.
