Refine gameobject chest interaction flow and remove temporary debug logging

- Keep WotLK chest flow stock-like by relying on GAMEOBJ_USE/REPORT_USE instead of forcing eager CMSG_LOOT.

- Preserve fallback eager-loot behavior for Classic/Turtle paths with bounded retries.

- Improve GO targeting usability by allowing gameobject pick/retarget in world click logic.

- Remove temporary loot/chest diagnostic LOG_INFO traces added during chest-open debugging.
