[IMP] hr_recruitment: improve UX of applicants list view

Currently clicking the 'Other applications' smartbutton on an
application redirects to a kanban view that does not have very useful
information.

With this commit, this smartbutton now redirects to the application list
view and adds small UX changes to this list view.
