Subject: [PATCH] [NO GBP] Fixes conveyor belt runtimes from screentips
 (#78478)

## About The Pull Request

In #78278 it looks like I missed confirming for `tool_behavior` when
mousing over on screentips, causing them to throw runtimes when not
holding the correct tool. Oops. This corrects that, now properly
providing screentips based on wrench and screwdriver mouseover.

## Why It's Good For The Game

Runtimes bad. 🐛 💥

## Changelog

:cl:
fix: Conveyor belts now properly show their new screentips on mouseover
with tools.
