[MIRROR] Makes some use of CONDUCT_1 in grille and door attackby. [MDB IGNORE] (#17513)

* Makes some use of `CONDUCT_1` in grille and door attackby. (#71286)

## About The Pull Request

- Airlock attackby now uses `CONDUCT_1` to check if the mob should be
shocked on attack
- Grille attackby now uses `CONDUCT_1` to check if the mob should be
shocked on attack
- You don't leave a fingerprint on grilles you attack (?)
- Fire axe is now conductive (it's made of steel?)

## Why It's Good For The Game

- Consistency is nice.
- If you have an item you don't expect to shock you, it shouldn't
randomly zap you anyways.
- Grilles are especially bad for this: It hard checked _glass shards_
when attacking, and _glass shards_ only. That's lame and nonsensical.
All non-conductive weapons should resist a spark.

## Changelog

🆑 Melbert
balance: Attacking a shocked door with an item that isn't conductive
will not shock you.
balance: Attacking a shocked grille with any item that isn't conductive
(not just glass shards) will not shock you.
balance: Attacking grilles with items no longer leaves behind a
fingerprint on the grille (?).
balance: Fire axe is now conductive.
