The extension question was hidden behind the results screen (Gitea#11)

Jesse, playing v0.7.8: "Solitaire game ended. I did not have an option
to extend the game by a day."

The engine and the Frame were right — checked before changing anything.
A solitaire game at the end of its timetable reaches awaitingExtension
with extensionVotes [null], and renderEnding writes "play one more Day"
into #actions. It then opens #resultsdlg, which is MODAL, so those
buttons were directly underneath a dialog whose only control was Close.

The results dialog now carries the question itself, hidden unless a vote
is pending: Play One More Day / End the Game Here, casting the same
game.extend intent. The #actions buttons stay as the fallback once it is
closed.

TODO.md #35 recorded extended play as verified on phoenix.local — over
the HTTP API, which renders no dialog. What was proven was that the
server supports it, not that a player can reach it. Noted there.

Rides along in the unshipped v0.7.9. 870 tests pass, one new.
