Add new worn unarmed weapons

[Saelfen]

Summary

Content "Add Impact and Skewer Knuckles"

Purpose of change

Add content to unarmed combat caused by the void left over by #48503. By this point, only 4 unarmed weapons exist in the game. I saw this as an opportunity to use infrastructure added in #41209 for top layer gloves to be used as unarmed weapons to give them a useful niche of their own.

Describe the solution

Create Impact Knuckles and Skewer Knuckles with stats based relative to existing items.
Impact Knuckles has 12 bash (same damage as a pipe), and Skewer Knuckles with 10 pierce ( same damage as a steel sewing awl). From a weapons damage perspective, they are relatively weak combat stat-wise, Impact knuckles being barely stronger than a cudgel which is craftable seconds after starting the game, and Skewer Knuckles being only slightly stronger than a steak knife. This is intentional since unarmed weapons should not be stronger than armed weapons due to leverage and reach.

Describe alternatives you've considered

Not make them at all

Additional context

Additional changes in this PR:
Moved previously unarmed weapons out of the unarmed json file since they are no longer unarmed weapons.
Removed Bolt cutters from studded gloves since studs do not need bolt cutters to make, only a hammer.

This recipe should be handled by their common tool quality of bolt turning, not specific items that happen to have bolt turning.

Changes as per code review:
Moved cestus from swords and blades to bludgeon
Added mandatory double spacing between sentences
take into consideration mass conversion and now only use 1 lump of steel per item
Reduce time to craft for both weapons from 8 hours to 4 hours
Reduce mass of both weapons; about half a lb per hand for impact knuckles sounds reasonable (about the weight of a hammer on each hand), and a quarter of a lb for each hand for skewer knuckles.
Reduce volume of both weapons; 300ml for both down from 500ml. It made no sense for them to be twice the volume of leather gloves (250ml)

You will need to call out in #dev-help to have a dev run tests for you

Did you mean unit tests? I ran them locally and they all pass below:

Those on site

Looks to me all tests are triggered automatically on commit since they're running now

for security reasons, github requires new contributors to be authorized to run tests that might be able to be malicious

fortunately, I have the authorization to hit that button for you

Re-PR'd in #49914 which also addresses merge conflicts and the move towards the new armor portion format
