Fix list handling for Uint8List and update canvas tests

Updated Control model to avoid treating Uint8List as a generic list. Refactored matplotlib chart examples for consistent import style. Added and updated integration tests and golden images for canvas, including a new test for drawing images from bytes. Also enabled the test for Image control with src_bytes.
