gramps e6abc13461 feat(scoreboard): a DEBUG-only "Simulate" switch, so the strip is provable in the preview
Creator (2026-10-30): pre-1.0, use DEBUG — add a toggle that simulates the ticker so the strip can
be SEEN and its compositing verified before a real stream.

The sample travels the REAL ScoreboardRecorder a stream uses (one new member, a gift of three, a
milestone, a $12.34 Super Chat), so what the preview shows is exactly what live events produce — a
fake renderer would prove nothing. Toggling off clears to an empty session, so the empty state is
visible too.

Debug-gated at COMPILE time: `DevelopmentBuild` is a const true in DEBUG / false in Release, and the
checkbox binds its Visibility to it. A shipped Release build therefore has no dev control at all,
rather than one hidden by a runtime flag.

Guard: ScoreboardSimulationTests — the sample lands all four tallies through the recorder, off clears,
and the panel + const pair exist in the Dual (DEBUG/Release) form.
