Persist list pagination and search in the URL

List pages kept the current page in local state, so clicking into an
asset and hitting Back remounted the list at page 1. A shared
useListQuery composable now mirrors the page (and search term) into the
URL query via router.replace across all 18 list pages, so Back restores
the page you were on and lists are deep-linkable. Page 1 with no search
stays a bare path; changing a filter resets to page 1; unrelated query
keys are preserved.
