Fix: Decode host-management and clipboard text as GBK/UTF-8 on non-Chinese systems

The 主机管理 dialog wrote client data (process names, window titles, net
connection state, software entries, IE history, favorites, services,
scheduled tasks, hosts) through the ANSI InsertItem/SetItemText path, which
re-converts through CP_ACP and garbles Chinese when the operator machine
runs a non-Chinese ACP. Decode each client string with its real code page
and write it via LVM_SETITEMTEXTW, mirroring SystemDlg::SetClientTextItem.
Scheduled-task columns are split by encoding: name/path/exe come from the
client as UTF-8 (BSTRToUTF8) while the status literal stays GBK. Also detect
a UTF-8 BOM in the hosts file so a Notepad-saved hosts (EF BB BF) no longer
shows "锘?" on its first line.

In the keyboard dialog, the clipboard preview edit was an ANSI-class window
filled via utf8_to_ansi (CP_ACP) + SetWindowTextA, so Chinese was replaced
with '?' before it reached the control. Rebuild m_EditClipText as a
Unicode-class window and write the UTF-8 clipboard text via SetWindowTextW,
matching the m_edit record control.
