A server's show_dialog (configuration and play) opens vanilla's
DialogScreen instead of being dropped: the header with the title and the
warning button, the message bodies in a scrolling column, the action
buttons packed into columns (MultiButtonDialogScreen) or side by side in
the footer (notice, confirmation). A button runs its click event: a
custom action goes back as custom_click_action, a command runs (in play;
in configuration vanilla only warns), show_dialog opens another dialog,
copy_to_clipboard copies. after_action closes the screen, leaves it, or
opens the WaitingForResponseScreen. The warning button opens the
"custom screen" warning, whose Disconnect leaves the server. clear_dialog
closes it, and so do the level loading screen and a disconnect. The world
and HUD blur behind it as behind any in-game screen.
Inputs come next; here they are not drawn and keep their initial values.
tools/server_e2e.py is a new harness: a vanilla 26.3 dedicated server and
one Horizon client. Its dialog check shows a dialog with /dialog show,
clicks a command button (the server's trigger), a custom action (the
server's debug log shows its payload) and a wait_for_response one, and
clears a dialog with /dialog clear.
