fix(nginx): increase max payload for secure site
fix(nginx): increase max payload for secure site

The default nginx maximum client size was small enough that I couldn't properly
upload all of my academic papers (for some reason a couple of them are
obscenely large files). This increases the maximum body size to 500M for
secure.wagstrom.net to avoid it rejecting larger papers with 413 errors.
