yuanyuanxiang c08315cd79 Fix remote desktop cursor cross-contamination across dialogs ...

The view-mode "forbidden" cursor was applied with SetClassLongPtr(GCLP_HCURSOR),
which mutates the cursor for the whole window class instead of the single dialog
instance. Opening a second remote-desktop dialog without remote control overwrote
that shared class cursor with IDC_NO, so the already-controlled dialog also began
showing the forbidden icon even though it remained operable.

Move the view-mode cursor decision into OnSetCursor, which Windows routes per
window, and remove the now-unused class-cursor assignments. Remote-control mode
and the remote cursor-shape path are left unchanged.

Also drop the dead m_hRemoteCursor member and the leftover GetIconInfo block
(which leaked hbmMask/hbmColor in ScreenSpyDlg), plus the now-unreferenced
m_bMouseTracking flag.
