Bug Description

A new search or filter keeps the page number and shows "No results found". Cause: packages/web-app-search/src/portals/SearchBar.vue:332 copies the whole query including page; packages/web-pkg/src/components/ItemFilter.vue:141-155 and ItemFilterToggle.vue:34-38 do the same.

Reproduction Steps

1. Search a term with more than one page and go to page 2.
2. Search a term with one hit, or change a filter.

Expected Outcome

Page 1 with the results.

Actual Outcome

page=2 stays in the URL; "No results found" and no pagination.
