Workshop fix

[eltank]

Summary

SUMMARY: Bugfixes "Make basecamp modular workshop usable"

Purpose of change

I noticed that the modular workshop added in #34156 is not actually usable, i.e. you can't tell NPCs to craft any of the workshop recipes that it's supposed to provide via the expansion menu. In fact, after you finish building all the modular upgrades, you can't even Tab over to the expansion any more. This PR makes it so that the workshop recipes show up in the expansion menu.

Describe the solution

By comparing the json for the modular workshop with the json for the old blacksmith basecamp expansion, I noticed that it was missing "blueprint_provides": { "id": "blacksmith" }. I hacked that into my save file and the workshop became functional.
While editing the json files to apply the fix to the blueprint I noticed some unnecessary duplication so I created _common recipes and mapgens and did some refactoring. I also cleaned up some discrepancies between the tools being added to the workshop and the tools being made available as blueprint_resources, and I touched up some of the descriptions.

NOTE: The fix is not retroactive. Anyone who already built a modular workshop will not benefit from this (but scroll down for workaround).

Describe alternatives you've considered

Not refactoring and applying the same fixes 5 times for each workshop variant.

Testing

Play testing. Created a new world, built a base with a workshop without the fix. Repeat after applying the fix.

Instructions for save file hacking to enable crafting in an already built workshop (use at own risk).

• Find the file that contains the JSON for your basecamp. Usually this is
  <game directory>/save/<world name>/o.0.0
• Open in a text editor
• Look for this text
  "provides":[{"id":"blacksmith_recipes_1","amount":1}
• Replace with
  "provides":[{"id":"blacksmith","amount":1},{"id":"blacksmith_recipes_1","amount":1}

Looks good, thanks for cleaning up the duplicated entries! I must've removed blacksmith when trying to fix another error, good catch.

Very nicely done, and thanks for going to the trouble of detailing the save edit, too!
