Vendor Tailwind via the standalone CLI; drop the Play CDN

Tailwind is now compiled from static/css/input.css into a committed static/css/tailwind.css by the standalone CLI, fetched on demand into bin/ (gitignored) so no Node toolchain is required. layout.templ loads the local stylesheet instead of cdn.tailwindcss.com. Adds a Makefile with generate/css/build/run/test/clean targets.
