feat(balance): make matchhead powder recipe more granular, related fixes for mortar and pestle recipes

[chaosvolt]

Purpose of change

This implements some tweaks to how match head powder is make to make it less clunky to use, along with some related changes to some other mortar and pestle recipes once I noticed that a few of the recipes to use mortar and pestle lack batch time savings when most have it.

Describe the solution

1. Set match head powder recipe to make 1 charge at a time, per 1 matchbook charge consumed. This makes it more granular, though more efficient as a side effect. Given match head powder isn't used for much besides primers (and are used en masse in that case) I feel it's not too wacky balance-wise. Time taken also reduced from 8 minutes to 1 minute, and to compensate for this increase in time per unit made it now uses the same batch time factor most other mortar and pestle recipes use.
2. Misc: Gave the ammonium nitrate and sulfur grinding recipes batch time multipliers too. Again used the same scaling nearly all recipes involving mortar and pestle use.

Describe alternatives you've considered

Chitin meal is literally the only mortar and pestle recipe to use a time factor of 83-3 instead of 50-3, we could tweak that.

Testing

1. Checked affected files for syntax and lint errors.
2. Ported JSON changes to test build, confirmed I make match head powder 1 unit at a time now and for 1 charge of matchbook each.

Additional context

Checklist

Side note: making the recipes for primers more granular would be nice too, but those have the issue of using cans, scrap metal, and the like. Unless we restrict them to only copper there's no easy way to make them more granular (and this would double the material usage too).
