Summary

SUMMARY: Bugfixes "Fix Blacksmith Survey option appearing on bulletin board."

revert the changes to recipe_primitive_field.json that were made in ##34455. This removed the "blueprint_requires": [ { "id": "not_an_upgrade" } ], entry from the blacksmith survey and fortification walls.

Describe the solution

mlangsdorf caught its absence during review.

Describe alternatives you've considered

Testing

Loaded up a game and built a camp. Made sure the survey wasn't an option anymore. I also checked after completing a survey expansion mission.

I agree the blueprint_requires is needed for faction_base_blacksmith_0. Guess I deleted that one by accident in #34455; sorry about that.

However, I stand by the other changes. blueprint_requires shouldn't be there in faction_wall_level_N_0 or faction_wall_level_N_1 because blueprint_requires doesn't do anything unless construction_blueprint is present. Should those other entries have a construction_blueprint field?
