chore: add build:ci smoke test to verify webpack build

Adds a build-ci make target (exposed as npm run build:ci) that runs openedx build against site.config.dev.tsx, and wires it into the CI workflow after the existing tsc-based build step. Catches errors in the real app graph (e.g. broken imports in lazy-loaded routes) that neither tsc nor Jest would surface.
