Makes chaplain armour have consistent wound protection (#92477)

## About The Pull Request

Eliminates the separate armour datums for chaplain helmets and clock
armour, which were identical to the regular suits apart from a missing
wound protection. These items now use the same armour datus as everthing
else.

Incidentally removes a useless redefinition of a var to the parent's
value, and adds missing time defines.

Fixes #92448

## Why It's Good For The Game

It makes more sense for these values to be consistent between matching
suits and helmets, and also between otherwise functionally identical
clock around and all the other sets.

## Changelog
🆑
fix: Chaplain helmets and clockwork armour now have the same wound
protection as the other chaplain body armours.
