Make the API and web images build and run

The image builds were never exercised: the docker job needs lint, and
lint was failing, so nothing downstream of it ever ran. Four defects
had accumulated behind that gate, each fatal on its own.

- pnpm creates no node_modules for a package without dependencies, and
  @source/shared has none. Three COPY lines named that path and failed.
- The production stage copied apps/api/dist, which tsc never wrote:
  tsconfig.base.json sets noEmit and no package overrides it. Rather
  than turn emit on — every @source/* package points main at its
  TypeScript source, and @source/proto derives daemon.proto's location
  from a /src/index.ts module URL — the stage now runs the sources
  through tsx, exactly as the migrate stage has always done.
- tsx lives in apps/api/node_modules/.bin under pnpm's isolated layout,
  so the command only resolves from the package directory.
- Both healthchecks probed localhost, which musl resolves to ::1 while
  the servers bind IPv4. Every probe was refused, so the containers sat
  unhealthy forever — and `docker compose up --wait`, which is how a
  panel installs this stack, waits for healthy.

Also fixed the postgres healthcheck in both compose files. pg_isready
without -h asks over the unix socket, which answers during the image's
init phase before the server listens on TCP; the migrate container then
started and died with ECONNREFUSED against a container Compose had just
called healthy.

Verified by running the full stack from docker-compose.panel.yml with
locally built images: migrations and seed complete, api, web, daemon,
postgres and redis all report healthy, and /api/health answers 200
through the web container's proxy.
