ids theme: rework the references slide layout and auto-fit it
Address four points of criticism on the bibliography slide:
- "Authors (Year):" no longer sits bold on its own line but runs
inline in a medium weight -- it was overemphasized for text that is
already darker than the entry, and looked blurred at small sizes.
- Entries get breathing room below the title bar (padding, so the
vertical-centering wrapper's first-child margin reset cannot eat it).
- Authors running inline saves a line per entry.
- The slide auto-fits: decreasing font sizes are tried and, when even
the smallest would overflow, trailing entries move onto
automatically created "References (cont.)" slides (Reveal.sync()
registers them, so navigation, menu and numbering keep working).
In print/PDF the scroll box is disabled so long bibliographies flow
across pages instead of being clipped.

## Bibliography and Appendix Slides
-When you cite with `[@key]` and set a `bibliography:` in the yaml header, the references are formatted with the bundled IDS citation style by default (based on the style developed for ICLC-10 2023 in Mannheim). To use a different style, specify it as usual with `csl:` in the yaml header.

Pandoc/citeproc generates the reference list **at the very end of the document body**. That is fine when the references are your last content:
