fix: Resolve login routing conflicts and network connection errors

- Redirect old /login route to /login-new to prevent conflicts
- Update logout API to redirect to /login-new instead of /login
- Fix network connection errors caused by inconsistent login URLs

This resolves the "Failed to load resource: The network connection was lost"
error that occurred when browsers tried to access the old login route.
