Style admin pagination widget, add missing locale keys

Pagination had almost no styling, and its current-page selector never
matched will_paginate's actual markup. Added chip-style page links, a
solid current-page indicator, and distinct disabled states for
Previous/Next.

Previous/Next/gap rendered as empty, unlabeled elements --
will_paginate only ships English translations and this app defaults
to German. Added previous_label/next_label/page_gap to en.yml and
de.yml.
