🐛 **Handle stale Livewire asset exceptions gracefully**

- ✅ Added detection logic for stale Livewire asset patterns to avoid 500 errors.
- 🛠️ Updated exception handling to return 404 for stale asset requests.
- 🔇 Prevented logging of stale asset exceptions to avoid unnecessary noise.
- ✅ Added tests to verify 404 responses and absence of log entries for stale asset scenarios.
