Subject: [PATCH] [MIRROR] [NO GBP] Power outage operation fixes for chem
 master (#2846)

## About The Pull Request
- If the chem master runs out of power mid printing, it will properly
stop the printing process and its animation
- When transferring reagents it correctly checks if we have enough power
without forcing it

## Changelog
:cl:
fix: chem master properly shuts down if it loses power mid printing and
won't transfer reagents for the same
