New/Changed Events Tuning (#20888)

First round of tuning after the addition of new electrical storms,
changes in behavior, etc. Details in the changelogs, but apart from
general balancing of event weights and effects, this PR also expands the
description info on Telecomms machinery to communicate that you need to
use Nanopaste to repair them (which I don't think was documented in-game
anywhere), and also adds a stack of Nanopaste to the TComms vestibule to
facilitate repairs if no one is around to produce the stuff.

Also you can beat Telecomms machinery with a stick to start garbling
them now! Take that, Medical channel!

There will probably be another round of balancing after this to make
sure the events all feel and play maximally right/fun.
