Open the info screen with Enter and move edit into it

Enter on a guest now opens its info screen, replacing i. The guest
table shows Enter as "Info" in the footer. A priority binding at app
level would have taken Enter away from buttons and lists in the
dialogs, so the hint comes from the table's own binding instead.

Editing cores, memory and disk moved from the main screen into the
info screen (key e). When the edit dialog closes, you are back on the
info screen. Test helpers that pressed i or e on the main screen now
go through Enter, because the requirement changed.
