demo scanner now properly works for incinerator tanks (#6544)

# About the pull request
will now display the stats of the reagent itself instead of the mix of
100 units. Will also display the caps of the tank instead if the reagent
goes above them
also fixes some grammar

# Explain why it's good for the game
bug fix good
grammar fix good

# Testing Photographs and Procedure
scanning a normal flamer fuel tank:

image is outdated. I added "fuel statistics" above intensity

# Changelog
:cl:
