[MIRROR] Reduces chat/audio spam when multiple ghost polls are being called (#26503)

* Reduces chat/audio spam when multiple ghost polls are being called (#81441)

## About The Pull Request

This slightly modifies the polling subsystem. The sound/chat popup for a
new role is now only given on the first "stack" of a role signup.

Let's say 3 loneops roll at once (ty admins), you'll still get the toast
popup for 3x loneop rolls, but you'll only get one text highlight in the
chat, and only one audio stinger.

Even if the first 2 loneops don't have anyone sign up for it, using the
text or toast signup options will still sign you up for the last roll as
it completes. This shouldn't make signing up any harder, just quieter.
## Why It's Good For The Game

Less spam in chat. Less headset-blasting audio bleeps. Cool!

Closes #80998.
