JakubandClaude Sonnet 5 5fbfd7c5f9 fix(ui): HomeScreen::poll() re-fired shutdown() every tick after the first
_shutdown_init (set true once KEY_ENTER is pressed on the Shutdown home
page) was never cleared, so this branch kept calling _task->shutdown()
on every single poll() tick indefinitely once triggered.

Invisible on real hardware: _board->powerOff() halts the MCU in the
non-restart path, so there's no next tick to matter. But
SimMainBoard::powerOff() is a deliberate no-op (no real hardware to
power off), so a sim instance keeps running after "shutdown" -- and each
repeated shutdown() call re-fires _display->turnOff(), which blacks out
its <canvas> (keyed by simInstanceTag) again on every frame.

This is what made meshcore-solo-site's RESET button unusable after a
device had been shut down: the still-running old instance kept
re-blacking the very canvas a freshly reset instance (same tag, same
canvas element) was trying to render its own boot splash onto -- visible
as a black screen, with the new instance's splash winning a single frame
every so often before being painted over again.
