CLARIN-DSpace v9/Port #1300 (accessibility sweep) to the v9 base (#1509)

* Port #1300 to dtq-dev-9-base: UFAL/Accessibility existing issues all (ufal#139)

Source: d154682 (dtq-dev PR #1300)

Adapted to v9: DsLangPipe reaches its six consumers through each standalone
component's imports[] instead of the removed shared.module.ts; the
clarin-description-item-field loop uses @for; the vanilla-9-only #linkImg
metadata-values template gets the lang binding too; the custom theme's
full-file-section override mirrors the new imports[]; the footer's <br/>-in-<ul>
fix is already on 9-base as li.list-spacer, so only the heading levels and the
matching .h4 SCSS selectors are ported.

* Cover the one behavioural change of #1300 with a real spec

clarin-description-item-field is the only component this port changes
behaviourally: it used to join every description value into a single innerHTML
with <br>, and now renders one <div> per value so each can carry its own lang.

That component had no spec on dtq-dev-9-base. dtq-dev has one, but it is a bare
"should create" smoke test that would not have caught any of this, and the
source commit did not touch it.

Adds five cases against the new shape: one element per value, per-value BCP 47
lang, no lang attribute for the wildcard language, makeLinks still producing
anchors through [innerHTML], and the empty-metadata case.
