Simplify build, revamp slides, add html2pdf

Remove per-course rendering/asset copying and simplify local build.sh output; add ignore for _quarto_internal_scss_error.scss. Disable Quarto execute.freeze (set to false) so code is re-run on render. Major redesign of r-and-rmarkdown/styles/slides.scss: updated palette, typography, layout, code/table/list styles, utilities, animations and dark-mode hooks to modernize the Reveal.js theme. Add tools/html2pdf.py: a Playwright-based CLI to convert Reveal.js HTML slides to PDF.
