When an online host has a remark set in the client list, use it in place of
the IP in the remote desktop ("远程桌面控制") and virtual screen ("远程虚拟屏幕")
dialog titles, falling back to the IP when no remark is present.
Add a GetTitleHostName() helper to both dialogs. CScreenSpyDlg resolves the
remark through its parent dialog's client map, while CHideScreenSpyDlg uses
the global g_2015RemoteDlg pointer; each falls back to m_IPAddress when the
host has no remark.

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.

Fixed two bugs when closing ScreenSpyDlg with file transfer dialogs:
1. Access violation (0xC0000005): CDlgFileSend self-destructs via
PostNcDestroy (delete this) when closed, leaving dangling pointers
in m_FileRecvDlgs map.
2. Double-free: Original code called DestroyWindow() then delete,
but DestroyWindow already triggers delete this via PostNcDestroy.
Solution:
- Store {HWND, pointer} pairs instead of raw pointers
- Check HWND validity with IsWindow() before accessing pointer
- Use SendMessage(WM_CLOSE) to let dialog self-destruct safely
- Always erase map entries to prevent accumulation of invalid data
