fix(webapp): don't count the column layout as filters in favorite names

The runs URL now carries cols/sc/hide, and describeFilters counts any param it
doesn't recognise, so favoriting a view with customised columns named it
"Runs: 3 filters" and added an inflated "+N" to genuinely filtered views. The
layout is presentation, not a filter, so it joins NON_FILTER_PARAMS.

The three param names were repeated as literals across four files, so they now
come from one exported list in the column registry.
