Add visibility controls for tile UI elements and plugin opts

Introduce visibility bindings for footer, settings, and chart buttons in MetricTile and MetricTileCustomUI. Update vmTile and plugin interfaces to support new visibility properties, allowing plugins to control UI element display. Add StopAllAsync to vmTile for async study shutdown. Minor cleanup in Dispose logic.
