Increased camera rotation; resolved getting stuck when changing headquarters.

【New Content & Balance Adjustments】

• Improved camera zoom speed. Expanded the freedom of camera angles, allowing the camera to look directly upward and downward (camera angle can be changed by moving the mouse while using the mouse wheel or holding the left Ctrl key).

【Bug Fixes】

• Fixed an issue where enemies could become stuck at the former headquarters after changing headquarters.
• Fixed an issue where enemy attack effects could remain visible for too long after the attack target had disappeared.
