Subject: Render asset credit inside the gallery lightbox correctly

GLightbox's own selector-based description feature never actually
resolved a selector in three different attempts -- literal text,
then a resolved-but-empty div, then apparently not firing at all
against the installed (unversioned) build. Replaced with a small
afterSlideLoad handler that reads a plain data-credit-selector
attribute and copies the real element's HTML into the slide's
description area directly, depending only on GLightbox handing back
a real DOM node per slide -- a much smaller contract than trusting
its own caption-resolution feature.

Renamed the credit div's class from glightbox-desc, since that name
is reserved by the library's own bundled CSS (display: none
!important) and can't be reliably overridden from here.

Also: distinguishes the credit line and the "N Bilder" caption from
ordinary body text (italic, muted, matching .author_and_date's
existing convention), and makes the lightbox's caption card follow
the site's light/dark toggle via Canvas/CanvasText, since the
library's bundled theme never adapts to it on its own.
