What does "active" mean in this context? Is there such a thing as an
"inactive" cold front, or is that just another way of saying stationary
front? Is there any difference between a "stationary boundary" and a
"stationary front"?

An active cold front would be one with frontal 'activity' associated with
it. Most likely there were some thunderstorms present.
