Refactor register_canvas_schemas by extracting helper functions

The register_canvas_schemas function was overly long. This commit refactors it into three smaller helper functions based on domain grouping:
- register_canvas_shape_schemas (for visual/shape elements)
- register_canvas_text_schemas (for textual elements)
- register_canvas_misc_schemas (for miscallaneous and animations)
