Switch templates to LuaLaTeX with fontspec

Moves paper, assignment, and letter templates from pdflatex to
lualatex, and replaces the Type-1 font setup (mathdesign/garamond,
ucs/utf8x, T1 fontenc) with fontspec using EB Garamond for the main
font and TeX Gyre Heros for sans. This produces PDFs whose text
extracts cleanly and is a prerequisite for tagged/accessible PDF
output.
