Fix: Decode client file path correctly in client list and info popup

The client reports its own exe path as UTF-8 in RES_FILE_PATH. Two
display sites re-decoded those bytes with the wrong code page and turned
Chinese paths into mojibake on non-Chinese servers:

- The client-list "程序路径" column wrote ProgramPath through the ANSI
  SetItemText path, so the UTF-8 bytes were misread as the system ACP.
  Decode UTF-8 to wide and write with LVM_SETITEMTEXTW instead (same
  pattern as the window/process lists).

- The double-click info popup normalized the client RES_* fields to the
  system ACP and rendered strText with CP_ACP -> wide. The app's internal
  ANSI convention is fixed GBK/936 (/execution-charset:.936 plus
  setlocale(".936")), so on non-Chinese systems the path collapsed to '?'.
  Normalize to 936 and decode 936 instead, which also fixes the popup's
  GBK labels and username in the same pass.
