Approvableness shows up in dictionaries; but outside of dictionaries Google Books shows me only five uses since 1900, and three of those are from a single book on Doing Phenomenology, whose author's native language appears to have been German.
I recommend you not use this word at all. The ordinary noun derivative for adjectives of the form VERBable is VERBability, so a better choice would be approvability. It's not exactly common, but Google Books lists several dozen uses in the current century.
As for your state vs quality question: this is pretty standard dictionary language for surrounding the meaning of a term when you can't quite pin down an actual 'meaning'. State and quality aren't distinct entities: they're two metaphors—where an entity stands and what it is like—for describing the endstate of recategorizing a verb as a noun.
