Reagent tanks can now be dragged faster (#5704)

# About the pull request

brings the drag delay of reagent tanks to 1 down from 3
they have wheels on the sprite so it makes sense
beer kegs, water coolers, pepper spray refillers, etc are adjusted to
default to compensate

# Explain why it's good for the game

its quality of life

# Testing Photographs and Procedure

it works

# Changelog
