Fix Fit to Frame: resize canvas to match output dimensions

Browse Source 
The fitted image was processed and inserted correctly but the canvas
(config.WIDTH/HEIGHT) was never updated, so the result was clipped to
the original canvas size. Now wraps both new-layer and replace-layer
paths in Prepare_canvas_action + Update_config_action so the canvas
expands (or shrinks) to the target frame size automatically.
