Console: DOSBox IPs (+100) checkbox on all four game pages

The DOSBox-X preservation pods run the original DOS builds of BattleTech
4.10 / Red Planet 4.10 inside an emulator whose bridged NIC is enumerated
100 above the host pod's last octet. A new checkbox on each game page
(RP Death Race / Martian Football, BT Free For All / No Return) shifts
every siteconfig address the page uses by +100 so the same pages control
either version of the games:

- Munga game connections (port 1501) target host+100; toggling the box
  drops and reconnects any requested pods at the new address.
- Mission egg player and camera entries carry the shifted address.
- The checkbox locks while a mission is loaded/running, like the other
  mission properties.

Launcher / site-management traffic is untouched -- those services still
run on the pod host itself. Pages share a pod's MungaGame, so the most
recent page to toggle or enable wins if two pages fight over one pod.

Verified end-to-end against vPOD: netstat shows the game connection move
127.0.0.1 -> 127.0.0.101 -> 127.0.0.1 as the box is toggled, and the egg
received by vPOD carries pilot=127.0.0.101. All 103 diff tests pass.
