GeoIP Admin Panel

TGUI report of every connected client's ping and GeoIP data. Read-only; lazily triggers a GeoIP refresh on any row whose status is not "updated".

Two independent ui_modules so the views never share window or state:

• /datum/ui_module/admin/geoip — full list of every connected client. Used by the View GeoIP admin verb.
• /datum/ui_module/admin/geoip/focused — one ckey only. Used by the GeoIP link on the player panel.
