Zone activities farm plots issue

# Describe the bug
After finishing with farming, if there are sort zones nearby, the character will being tidying up, but sometimes, they go to places with no zones in them and do... something? idk.

# Steps To Reproduce

Make farm plot zone
make sort zone
commence autofarm
watch your character maybe do something they shouldnt do

# Expected behavior
Not going to places without zones and doing stuff

# Screenshots

# Versions and configuration

Tried on dda only, build 11495

# Additional context
I wish you could just turn off 'tidy after autofarm'

Start by reproducing the reported sequence: create a farm plot zone and sort zone, commence autofarm, and observe the post-farming tidy behavior. Trace the autofarm cleanup path to determine why the character visits areas without zones; done means cleanup stays within relevant zones, with any separate toggle request treated as additional scope.
