vPOD: real C:\Games installs, optional real app launching, power-group swap

- InstallProduct now extracts into the real C:\Games (the launcher's
  GAMES_DIR) so deployed products land where their catalog launch entries
  point; uninstall removes the real product folder. Tests pass an isolated
  games root through the VirtualLauncher ctor.
- New "Actually launch apps (real processes)" toggle (off by default =
  simulated PIDs): LaunchApp starts the entry's exe exactly like the Agent
  (same start info, same registered-but-not-installed error), Kill*/
  Uninstall/Wipe terminate the real processes (kill before folder delete),
  and self-exited apps are pruned from GetLaunchedApps/FullUpdate. Real
  processes die with the machine: power off, reboot, or closing vPOD. The
  Agent's autoRestart watchdog is deliberately not emulated.
- Pod Power and Mimicking Game groups swapped (game left, power right).
- Provisioning round-trip test now skips as inconclusive when a running
  TeslaConsole holds UDP 53291 instead of failing the suite; two new tests
  cover real launch/kill (ping.exe) and the missing-exe error path.
