What's with the automender change?

[Splints]

I don't have an opinion on the change, but the reasoning for the change is outlined in the pull request here https://github.com/goonstation/goonstation/pull/5747

Quoting Kyle:

This aims to pivot the Auto-Mender from being a ubiquitous healing item that everybody and their mother has on them, to a specialized tool for doctors. We want them to have a high value item for doctors, and everyone really. Like a Security Officer's stun baton. You'll not want to just throw it away when it runs out of "charge" or let anyone take it from you.

As to the other part of the rationale behind this change; it's that currently with all the menders everywhere, it's been a bit trivial for anyone to very quickly heal themselves from even extreme damage without the aid of another player. This is sort of a symptom of chemistry being essentially the only reasonable way to heal from anything, but these menders everywhere puts those in the hands of everyone for too cheap.
