The Win32 EDIT control caps text at ~32K/64K chars by default, so the
client log dialog silently stopped accepting appends long before the
512KB truncation logic could run. Call SetLimitText(0) in both
CClientLog and CActivityDialog to lift the cap.
Also unify newline handling in Logger: each entry now ends with exactly
one '\n' at the source, so the in-memory ring-buffer dump (used by the
TCP log query) splits into lines correctly instead of relying on every
Mprintf caller ending its format with '\n'. writeToFile drops the extra
std::endl accordingly.
Additionally fix a CFont leak in CClientLog::OnInitDialog by moving the
font to a member.

Record the client's active-window history (start time, window title, and
dwell duration), newest first, skipping dwellings under 5 seconds and
breaking the timing on idle, capped at 500 entries. Add an "Activity
History" item inside the host's Client Management submenu that requests
the snapshot over the main connection and shows it in a new dialog. The
dialog rebuilds its edit control as a Unicode window so UTF-8 titles
render correctly instead of degrading to "?" through the MBCS ANSI
boundary. The menu item and dialog title go through _TR and are
localized in en_US and zh_TW.
