fix: keep Rating + Tags pills in their sections, only hide Flag in Discarded

Rated and Tags sections still benefit from their respective pill —
Rating because the user can refine the section's ratingMin >= 1 to a
higher floor, Tags because they can intersect the tag-grouped view
with a specific tag id list. Flag in Discarded is the only pill where
the section locks the only useful value, so it stays hidden there.
