[MIRROR] Blood filter surgery update (#28486)

* Blood filter surgery update (#84431)

## About The Pull Request

Updates the blood filter surgery step to be less chat and sound spammy,
only going 'ping' when it's completed filtering blood as the text
message implies. During the filter running process instead the sound is
a softer hum.

## Why It's Good For The Game

We have progress bars above our head and cogwheels to other viewers. We
don't need two text log lines and a 'ping' every time it runs the filter
loop. It should only say completed and ping when it's actually
completed.

## Changelog

🆑 LT3
code: Blood filter only pings and says finished when it's actually
finished

* Blood filter surgery update
