Fix `zinc_metal` stats (and cascade effects)

[cake-pie]

Summary

Bugfixes "Fix zinc_metal stats (and cascade effects)"

Purpose of change

Split off from #62936

The density of zinc_metal is way off. Fix it, and deal with cascading effects in recipes.

Describe the solution

Zinc has density 7.14g/cm³. That's 357g for 50ml volume, which divides into a stack of 200 charges, 1785mg per unit.  

Adjust the disassembly of 5L zinc ingot, applying a 5.5% lossiness -- as I work my way through the spinoffs of #62936, 5~6% loss rate that will be applied consistently to all 5L ingot disassembly.  

Migrated item zinc oxide with misleading id chem_zinc to chem_zinc_oxide to prevent confusion with actual elemental/metal zinc items. Drive-by adjustment to volume due to discrepancy in quoted density figure -- not expected to affect recipes, since those depend on the weight (which corresponds to 1/100 moles of chemical).  

Fix weight of coal_lump, from 1.5g to 37.5g. There was a mistake in 5549b62 where divided by count (250) instead of stack size (10) leading to value off by a factor of ×25. This is required for sanity of the next step.

• [x] check cascade effects of coal weight change; see details below  

Fix recipe for smelting zinc_metal from ore material_zincite by reduction with carbon.

• Quantities reworked on the basis of zinc content of zincite, to ensure balanced input and output.
  • Zincite composition: Zn_0.9Mn²⁺_0.1O [source]
• Added hammer and chisel tool requirements to break ore and coal into smaller pieces before roasting; would not work if you just chucked a large chunk of ore in.
• Replace basic boil and contain requirements with crucible due to high temperatures.
• Added fuel required for roasting. This is distinct from the coal being used as source of carbon reagent. Smelting roughly 1.5kg of mass in total, or 6 steel-chunk-equivalents.  

Adjust recipe for grinding of zinc_metal into chem_zinc_powder; reworked to produce ~130g, on the same scale as aluminum powder grinding recipe (176g output) and maintaining roughly the same material inefficiency as before (was 1308g/1400g, 6.6% lossy). This only balances zinc input and output, other issues with this recipe are marked with TODO and deferred to be fixed as a package with other problems found with powdered metals in #62936  

Adjust battery recipes by scaling zinc_metal inputs to roughly preserve mass. However, proportion also needs to be preserved when comparing among those recipes, so it is a straightforward scaling by 4× rather than 3.922× followed by rounding. (This is naive multiplication only, I did not look into the scientific basis for these recipes.)  

This should cover all pertinent references to zinc_metal in src/, data/json/ and data/mods.

Testing

Suggested checks:

• Double check my maths / chemistry derivations.
• Load in game and check
  • zinc metal and coal lump have sane stats
  • 5L ingot disassembly recipe reports sane input/output in crafting menu
  • check zinc smelting recipe in crafting menu for sanity
  • check zinc powder grinding recipe in crafting menu for sanity
  • check battery recipes in crafting menu for changes applied correctly.

Edit: none of this is applicable any more due to #62180

~Adjustments to usages of coal_lump going to be listed here because it's kind of a spinoff sub-issue so it's neater to keep it separated from the zinc_metal stuff.~

Fix recipe for further reduction of zinc oxide with carbon; this uses an extremely conservative approach that oversupplies carbon.

• takes a hint from this, "to achieve the complete reduction of ZnO, the amount of reducing agent was increased to two times the stoichiometric amount."
• the charcoal amount was simply scaled together with the coal lump amount. checking for correct equivalence between them is deferred, see below.

---

CaC₂ production: looks like I need to make a separate PR related to the arc furnace process, so I'll deal with it there.

• #63392

---

Innawoods ammonium hydroxide recipe: skipped, because this was a hack to compensate for inability to loot the chem in innawoods, and I couldn't figure out what kind of process this was supposed to be based off of.

---

Several recipes allow coal_lump and charcoal to be used interchangeably, in equal or unequal amounts -- there isn't necessarily a consensus on the conversion rate between the two, although 1-to-1 is common. The usage may treat them as fuel, and sometimes as a source of carbon. Further scrutiny is required for the correct ratio between the two alternatives, and that is ~being deferred to a separate PR.~ already being worked on in #62180

Besides the reduction of zinc oxide with carbon from above, other such instances are:

• data/json/requirements/materials.json: requirements for CVD coating,case hardening steel
• data/json/recipes/armor/other.json: carbon for rebreather_filter
• data/json/recipes/recipe_others.json: tempered steel wire; survival_marker
• data/json/recipes/other/materials.json: smelting of 3 different grades of steel
• innawoods: smelting of steel_lump + 3 different grades of steel

A note regarding ore processing: The hammer+chisel requirement isn't an issue here, but be careful when you get to iron ores, as we don't want to put Innawood in a catch-22 situation where you need the tools to process the ore you need to get the tools. For that case it might be useful to add an additional recipe that uses more primitive tools at the expense of it taking longer.

Couldn't Innawoods issues be handled in Innawoods-specific recipes? It's a bit weird to adjust mainline recipes specifically to avoid problems in Innawoods. I had the same thing happen when I changed the antenna recipe and made electronics not able to be learned in Innawoods anymore - I just ported the old recipe that allowed for it to be Innawoods-specific.

[PatrikLundell]

Yes, I would suggest it would be an Innawood specific recipe. However, this PR is tagged with Innawood, so I didn't think to mention that specifically.

[cake-pie]

The tagging happened automatically because in this PR I have adjusted the innawood version of the battery recipe alongside the mainline one when adjusting input amounts.

Noted the potential smelting catch-22. Depending on the ore's hardness, I guess you could just try smashing it with another rock of harder material, or something like that.

[PatrikLundell]

Come to think of it, bog iron isn't actually huge chunks of rock, so it wouldn't need much or any bashing in the first place. Thus, hematite could use the regular breaking apart routine, while the Innawood specific bog iron might not actually need any tool change. Even if that's needed, pulverizing it with a rock (hammer 1) ought to be sufficient.

~Ready for review but not merging -- will rebase after #63365 is merged, dropping 21c4214.~

[anoobindisguise]

I already fixed the weight of coal (and charcoal) in pending #62180. this will conflict.

Noted, thanks for the heads up

[cake-pie]

Rebased to incorporate changes from #62180.
