OnTapCallback class abstract

Light-weight (callback_id, payload) pair used as the image-tap action on RichImage and ImageComponent. Distinct from RichAction because image taps never need a label or visual style — they just dispatch through the same host-supplied OnCustomCallback channel that buttons use.
