build: add workbox-window as explicit devDependency

Required for pnpm strict-hoisting builds (used by aiolabs/server-deploy
NixOS builds). Without it as a direct dep, Rollup can't resolve
`workbox-window` from vite-plugin-pwa's virtual:pwa-register module —
npm's flat hoisting masked this previously.
