Makes miner callouts compatible with pet commands, they start off by default (#96747)

## About The Pull Request

Closes #87571

Callouts now use an override of pointing code rather than an entirely
separate visual, which means that they can trigger pet commands now.
Also, they start off by default.

## Why It's Good For The Game

Callouts are only useful if you're mining with a buddy, so leaving them
off by default is a sensible choice since most of the time that's not
the case.

## Changelog
🆑
qol: Miner callouts are now off by default
fix: Miner callouts can now be used to command pets like regular
pointing
