Fix not being able to fetch tools (disassembly zone)

[Menschheit]

Summary

None

Purpose of change

1. One of the variables I defined was overwritten by a local variable during copy&paste.
2. Should not use default parameter(clear_path = true) in crafting_inventory,
3. Only the player can do handle_liquid.

Describe the solution

1. Fix my dumbness.
2. Add false to the arguments.
3. Restrict NPCs from the high-end work which they can't deal with.

Describe alternatives you've considered

Testing

Tested with my own save and it worked, but that's not enough I think.

Additional context

If all the items on the same tile have some different unfulfilled requirements, only the last requirement count for fetching action (and it represents the requirements for that tile). So even there are enough (fetchable) tools for other items except the last one, you still can't fetch them.
At the moment I don't have an Idea how to solve the problem without rewriting quite some codes.
