Expand merchant storage space

[MNG-cataclysm]

Summary

Bugfixes "Give merchants greater pocket space for buying things"

Purpose of change

Some stationary merchants could only buy items within their pocket size, despite having shelves and crates for storage. I've added the proper zones to allow stationary merchants to buy large, bulky items. PR #59805 is a good example of the methods I used.

Describe the solution

I gave several NPCs the shopkeeping mission status and added unsorted and currency loot zones to their shops.

Describe alternatives you've considered

Giving the merchants larger storage clothing, such as giant novelty backpacks or more duffel bags.

Testing

I spawned a character, teleported around, and sold 10L bricks of aluminum to various people. They all accepted the trade, and put the ingots to the side.

Additional context

This will fix issues #61530 and #58604. Additionally, wait timers have been made NPC-specific for lumber merchants and chemists.

Have you tested that it still works when the location maps are rotated? There's otherwise a risk the zones end up being fixed regardless of the rotation of the trader location.

I tested it, and the zones rotate with the map.
