feat(library): rebuild the browse header as a title row and one command bar

Library, smart scope, collection, authors and series pages share a new
BrowseHeader: the place and its actions on one row, then search, sort,
filters and facets in one bar that folds groups instead of wrapping.
Format chips count from the new POST /libraries/:id/books/facets, built
on the listing's own query; scopes and collections gain filter and sort.
