templates/browse/search: Slightly modify search results UI
Rename "Visit type" back to "Origin type" as this is more comprehensible for a user not familiar with SWH data model.
Rename "Visit status" to "Archiving status" and simplify some tooltips for the same reason.
Wrap some long code lines in origin search related Javascript code.
Closes #2320 (closed)
