Fixes index error in inverse kinematics

Corrects an index error in the inverse kinematics calculation that occurred when resetting joint states after each iteration. The loop variable `i` was incorrectly reused from the outer loop, leading to out-of-bounds access when `len(joint_ids_sorted)` differed from `max_iter`. This change ensures correct joint state updates during inverse kinematics solving.
