Playsound to_chat respects admin music preferences (#95088)

## About The Pull Request

When requesting an internet sound, all clients connected to the world
receive a 'to_chat' with song information, even if they have 'Admin
music volume' set to 0.

This PR makes it so this 'to_chat' isn't sent to players who have 'admin
music volume' at 0. Why add a very intrusive chat-spam if I do not want
to listen to admin MIDIs?

Marking this as a fix because I can only imagine that this not being the
default behavior is unintended from the get-go.
## Why It's Good For The Game

Reduces chat spam for users who opt-out of listening to admin songs.

## Changelog

fix: Play Internet Sounds will now only display song details to users
who have admin music enabled.
