v1.0.51: stop chasing auto-refresh, tell the user to confirm manually instead

v1.0.49's panel-polling approach and v1.0.50's diagnostic logging did
not produce a working auto-refresh in testing -- the panel still hung
after the restarting message until a different button was clicked.
Rather than keep guessing at Stream Deck's PI-reconnect lifecycle,
removed the polling/debug scaffolding entirely and changed the final
status message to explicitly instruct the user: 'Updated to vX. Click
any other button above to confirm version update has been successful.'
