Feature: Machine management (主机管理)

Migrate the MachineManager client from SimplePlugins and wire the server toolbar.

Client:
- Add CMachineManager (process/window/net/software/IE history/favorites/service/task/hosts
  enumeration plus process injection via yapi.hpp).
- Add COMMAND_MACHINE_MANAGE (162) and spawn the manager on an authenticated
  sub-connection in KernelManager.
- Register MachineManager.cpp/.h and yapi.hpp in both client projects.

Server:
- Add the 主机管理 toolbar button (index 18, after 远程交谈) reusing the IDI_MACHINE icon,
  plus en/zh_TW/de translations.

Fix:
- Free the IEnumSTATURL strings (su.pwcsUrl/su.pwcsTitle) with CoTaskMemFree, release the
  enumerator, and set STATURL.cbSize to stop the IE-history leak reported by VLD.
