Add edge cache headers to all API routes to reduce Vercel function invocations

All API routes serve static content that only changes at deploy time, but had
0% cache hit rate. Adding s-maxage=86400 lets Vercel's CDN cache responses at
the edge, which should take the ~28K daily API requests from 0% to ~99% cache.
