Subject: [PATCH 3/5] CI/frontend: Add missing install flag for `prod` flavor

Also restrict linting, which requires dev packages, to the `dev`
flavor.
This makes the frontend build setup indentical to the backend.

Subject: [PATCH 4/5] CI: Use `npm ci` instead of `npm install`

`npm ci` is recommended instead of `npm install` for automated builds.
Its main advantage is the `package-lock.json` consistency check: The
command fails if the lock file doesn't match `package.json`.

Subject: [PATCH 5/5] CI: Add `--no-optional` flag to prod flavor

This ensures that the packages build successfully even when optional
deps are unavailable.
`--no-optional` currently has no effect on the backend, because
it has no optional packages.
