No functional change. Adds streamDeck.logger.info() calls at
onPropertyInspectorDidAppear, sendProjectsToPI(), and onSendToPlugin
entry, plus a small on-panel debug trail (property-inspector.html)
that timestamps $PI.onConnected firings, button clicks, poll sends,
and received payloads. v1.0.49's panel-polling fix didn't visibly
work in testing and produced no status text at all on the second
attempt -- need to see the actual event sequence rather than guess
again. Remove once the refresh flow is confirmed working.
