fix: CTA pre-buff no longer depends on broken BC/BO skill templates

Removed the visual skill check (is_right_skill_selected BC/BO) that always
failed because the BC.png/BO.png templates do not match D2R icons. New flow:
switch weapon, cast BC, cast BO, buff, switch back. Only verifies swap-back
by matching the original skill icon via template matching.
