Fixes wheelchair TTV logging, prevents detonation when stunned/timestopped (#91010)

## About The Pull Request
Wheelchair bell detonation did not give any fingerprints to the bomb,
resulting in the person who attached it not being logged anywhere. The
bell action could also be used while stunned or paralyzed, allowing you
to blow yourself up during timestop which is a bit silly.

## Why It's Good For The Game

Makes admins job easier, fixes an oversight/exploit.
