- Add image loading validation before sending canvas data to server
Prevents 'Failed to get confirmation' error when images haven't
finished loading after workflow reload. Waits 100ms and checks
if all layer images are complete before rendering output.
- Improve layer loading error handling in CanvasState
Better logging when layers fail to load from IndexedDB.
Allows empty canvas as valid state instead of failing.
- Add ResizeObserver for canvas container
Fixes bug where canvas only shows in top half of node.
Watches container size changes and triggers re-render to ensure
canvas dimensions are correctly calculated after DOM layout.
