Fix Nametag update failing with missing tailwindcss module

npm ci during update ran with devDependencies omitted, likely because
NODE_ENV=production was already present in the environment by then
(npm's documented default: omit=dev when NODE_ENV=production). Since
@tailwindcss/postcss is a devDependency, the subsequent `npm run build`
failed with "Cannot find module '@tailwindcss/postcss'". Force devDeps
to be installed regardless of NODE_ENV via --include=dev.
