Add configurable image overlay settings

Introduce configurable image overlay options and persist them. Added new state fields (image_width, image_offset, image_enabled) with defaults and wired them into the image overlay: the image display now respects the enabled flag, uses image_width for scaling and image_offset for placement. Extended the Settings dialog (resized, API field sizing) with a new Image tab containing enable checkbox, width and offset spinboxes, and included these values when saving. Updated config read/write to include an Image section so settings persist across runs and extended save_settings to accept image_width and image_offset. Minor import/order cleanup in image dialog.
