🧹 Fix empty catch block in App.jsx sonic escalation

[BTawaifi]

🎯 What: The code health issue addressed
Added a console.error log to the empty catch block within the useEffect handling the "Sonic Escalation" protocol in src/App.jsx.

💡 Why: How this improves maintainability
Silently swallowing errors makes debugging very difficult. In this case, if the Web Audio API (AudioContext) fails to initialize, create nodes, or play, it would fail silently. Logging the error provides visibility into why the audio escalation might not be working in production, improving maintainability and ease of diagnosis without altering the behavior of the application (the error is still caught).

✅ Verification: How you confirmed the change is safe
Ran npm install and npm run build (Vite client build), which both passed. The only change was adding console.error('Failed to play sonic escalation:', e); inside the empty catch block which doesn't affect existing functionality or flow.

✨ Result: The improvement achieved
A healthier codebase that properly logs unexpected errors rather than hiding them.
