Cleans up signal use in bitrunning [NO GBP] (#79426)

## About The Pull Request
Atomized #78997
Broke up duplicate signal usage - though they do the same thing, this is
convention & it makes it easier to debug
Removed custom alert subtypes in favor of just setting values directly
Removed some unnecessary vars like the console ref from the server
Since I'm just copying this over, it has added exam text for net pods,
which fixes an issue reported to me in Discord
## Why It's Good For The Game
Code improvement
## Changelog
🆑
add: Added some clarity to the range of netpods (4 tiles) in their exam
text.
