[MIRROR] Traitor Traitor Panel Fixes (#26561)

* Traitor Traitor Panel Fixes (#81521)

## About The Pull Request

- Fixes #81514
- Setting TC checked for `value && isnum(value)` which was dumb when
`value` could be `0`.

- Removing Traitor auto-takes uplink from the mob

- Removing Uplink now removes just the uplink code from memory, rather
than all memories

## Changelog

🆑 Melbert
admin: You can now set someone's TC to 0
admin: Removing Traitor from automatically removes the uplink from them
admin: Removing Uplink from someone no longer wipes ALL of their
memories
/🆑
