presentation.org: clean rewrite based on document.org

Same packages and color definitions as document.org, adapted for beamer:
- No longtable/ltablex (beamer doesn't support them)
- No geometry/fancyhdr/titling (beamer handles layout)
- No frame/tabular renewenvironment hacks
- Table scaling via config.el resizebox filter
- Frame breaks via config.el org-beamer-frame-default-options
- Madrid theme + Kyndryl palette colors + logo
