Equip from skill detail now updates the live skill bar at once

Equipping a skill from its detail sheet patched the persona but never pushed the
new bar to the on-field hero, so the skill only became usable after switching
heroes or dying/respawning (which rebuild the player). The detail equip handler
now calls comboCtrl.setHeroSkills(resolveEquipped(hero)) like the bar-management
path already does — the engine bar + buttons rebuild immediately.
