Bugfix pile (#22823)

Fixes several runtimes from the past few weeks, some additional material
repath regressions, and the fact that if I shoot you with a stream of
ionized deuterium particles, it doesn't riddle you with cancer.

changes:
- bugfix: "Fixes emergency shields runtiming when hit by thrown
objects."
  - bugfix: "Fixes several stale global list runtimes."
- bugfix: "Fixes several health percentage checks that could use unset
initial health values."
  - bugfix: "Fixes additional materials regressions in INDRA code."
  - bugfix: "Fixes invalid fuel injector depletion math."
- bugfix: "Makes accelerated particles apply radiation damage to living
mobs they pass through."
