fix(web): add workbox-window as explicit devDependency

vite-plugin-pwa's \`virtual:pwa-register/svelte\` imports workbox-window
at build time. The package was resolved transitively via @vite-pwa/
sveltekit but not installed in the webapp's own node_modules when
pnpm fetches only the workspace deps in a restricted Docker context.
Result: Rollup 'failed to resolve import "workbox-window"' at build.

Pinning the direct dep so the Docker build picks it up in the
filtered pnpm install.
