fix: enable scale/rotation on annotation objects and restore transforms on load

- Remove hasControls:false and lockScaling from markers so resize/rotate handles appear
- Add setActiveObject() after creating arrows and rectangles for immediate control visibility
- Restore angle, scaleX, scaleY when loading saved annotations (all object types)
