Previously, image annotations for signature seals used a static yOffset when combined with ink annotations, which caused positioning issues. This change calculates the y-position of the signature annotation relative to the next annotation and applies it only for the first seal. - Added `yPosOfSigAnnot` calculation for precise vertical placement. - Updated `AddInstantJSONAnnotationToPDF` to overwrite bbox.y for seals. - Removed hardcoded ink offset logic.
