fix(docker): add missing pnpm-workspace.yaml COPY in deps and runner stages

Without pnpm-workspace.yaml, pnpm install --frozen-lockfile can't discover
the apps/api workspace member, causing "Already up to date" and tsc not found.

Also removes stale packages/* entry from pnpm-workspace.yaml (no packages/
directory exists in the dev branch).

Fixes: GRO-1231
