Fix template syntax errors in page_header integration

- Fix department_list.html: use variable for create_url instead of inline yesno with url tag
- Fix feed_list.html: properly handle conditional create_url with with blocks
- Fix document_list.html: use variable for create_modal instead of inline yesno
- Fix request_list_full.html: simplify scope toggle by placing it separately after header

Django templates don't allow nested template tags in include parameters,
so we now prepare variables beforehand using if/with blocks.
