Optimized Ladder Function

● Changed "Log" to "Wood".

● Fixed the bug where picking up a backpack dropped after death would instantly spawn some zombies.

● Optimized the ladder function. Now, when approaching a ladder, a prominent prompt will appear. Also fixed the bug where players would get stuck when climbing up, or suddenly fall when climbing down.
