Feature: TCP/UDP connection management with force-disconnect

Add a connection-management feature to YAMA: a toolbar button (after MCP)
opens a dialog listing the managed host's TCP/UDP connections, with
right-click force-disconnect for IPv4 TCP rows.

Client: a new CConnectionsManager enumerates connections via iphlpapi
(GetExtendedTcpTable/GetExtendedUdpTable, IPv4+IPv6) and answers the
refresh and kill commands over a sub-connection.

Server: a new CConnectionsDlg (DialogBase) shows the list with sortable
columns and a right-click menu; the title-bar icon reuses the toolbar's
connection icon (res/connections.ico).

Fix byte order found during review: iphlpapi returns an IPv4 address as a
network-order DWORD and the port's low 16 bits in network order, so
storing them raw made the dialog show reversed IPv4 addresses and ports.
The client now stores addresses as network-order bytes and ports as host
order (ntohs), and reverses the conversion on disconnect.
