You forgot the braces for the argument of \framed.

1. Add a rule at the top of the footer.

\setuppagenumbering
   [location=footer]

\setupfooter
   [text]
   [before=\hrule]

\starttext
\page[dummy]
\stoptext


2. Put the page number in a frame (preferred method).

\setuppagenumbering
   [location=]

\setupfootertexts
   [{\framed[width=max,frame=off,topframe=on]{\pagenumber}}]

\starttext
\page[dummy]
\stoptext
