Make generated Vue monorepos buildable with docker compose

Running `draft new monorepo` with the Vue client and then
`docker compose build client` failed three separate ways, each found by
actually doing it:

- No Dockerfile: the Vue overlay never shipped one. The template now has
  an nginx-based image (project-template#4) and the client-vue sync job
  embeds it plus its nginx.conf.template, with the pnpm pin rewritten to
  the local version like the Nuxt overlay.
- Stale root lockfile: the Vue scaffold wrote a pnpm-workspace.yaml into
  apps/client (to approve vue-demi's build script), which made it its own
  workspace, so the installs updated a nested lockfile and the root one
  kept describing the template's Nuxt client - pnpm install
  --frozen-lockfile then refused it. The file is only written when the
  client isn't already inside a workspace (standalone `draft new client`).
- Missing component: the client-vue job listed components by name, so the
  AuthCard.vue that Login/Signup import was never embedded. It now embeds
  src/components/ as a whole.
