Pin tailwindcss and check the committed stylesheet against it (closes #231)

make css ran whatever tailwindcss binary was on the host's PATH, so the committed stylesheet depended on the machine that built it, and nothing noticed when a template used a class the stylesheet lacked. make css now runs the standalone tailwindcss v4.2.1, pinned by sha256, in a Dockerfile stage, and a check stage, run by make check and required by the image build, fails when the committed static/css/tailwind.css differs from what the templates need, showing the differing rules. input.css names its sources. The unused .btn-text is removed and the stylesheet regenerated, dropping only unused rules. The README has a Stylesheet section. Model: opus-5-5
