Project Topics UI polish and dropdown issues

The current topics page has a few issues that should be addressed by UX and dev.

  1. Polish current page background and header separation between breadcrumbs.
  2. Sorting dropdown seems broken. Corner case/nothing to do - see #437102 (comment 1714201932)
  3. Consider adding enhanced pagination that indicates page numbers.
  4. Consider modernizing the filter menu. Visibility could become a filtering element.
  5. Consider repositioning the subscribe icon

Proposal (WIP)

  1. Consider aligning the topics page with the newly re-designed project overview page. That would involve removing the header background color, and left-aligning the content, following the styles on the re-designed project overview page.
