Fix proxy stop not killing aware-cam-proxy.exe processes

The stop handler was targeting the wrong executable name
(aware-cam-proxy-win.exe instead of aware-cam-proxy.exe), so taskkill
never found the running process. Also removed dangerous fallbacks that
killed all cmd.exe processes system-wide and deprecated wmic calls.
Simplified to a single targeted taskkill. Launch now uses a unique
window title and cmd /c so terminals close naturally after the proxy
exits.
