fix(api): bundle packages/transitous-core into the image (cli depends on it)

packages/cli (shipped in the api image for admin-cli.ts) gained an
@openmapx/transitous-core workspace dependency during the transit refactor, but
the api Dockerfile never copied that package — so pnpm install fails with
ERR_PNPM_WORKSPACE_PKG_NOT_FOUND. Latent until a build-cache eviction re-ran the
deps layer. Copy its package.json into the deps + prod-deps installs and its
source into the runner, mirroring the data-manager image fix.
