Chest-type game objects (quest pickups, treasure chests) now send
CMSG_LOOT directly with the GO GUID instead of CMSG_GAMEOBJ_USE +
delayed CMSG_LOOT. The server's loot handler activates the GO and
sends SMSG_LOOT_RESPONSE in one step. The old approach failed because
CMSG_GAMEOBJ_USE opened+despawned the GO before CMSG_LOOT arrived.
Double M2 bone and material descriptor pool sizes (8192 → 16384) to
handle the increased NPC count from the spline parsing fix — patrolling
NPCs that were previously invisible now spawn correctly, exhausting
the old pool limits.
