"""FRREP-SR004 — the Search page exposes real type/collection/language filters.

Before this fix, search.html only had an author text filter even though
`search_documents()` already supported document_type/collection/language
(and more). These tests lock in that the filter controls are rendered and
that picking one actually narrows results via the real view.
