fix: delete textBox and rectangle from scene when removed

Similar to the connector fix, these reducers now properly clean up scene data when items are deleted. This prevents orphaned scene entries that could cause rendering issues and memory leaks. - Fixed deleteTextBox to remove from scene.textBoxes - Fixed deleteRectangle to remove from scene.rectangles - Added comprehensive tests for both reducers (60 new tests)
