ci(frontend): Speed up E2E test job (#12090)

The frontend `e2e_test` doesn't have a working build cache setup,
causing really slow builds = slow test jobs. These changes reduce total
test runtime from ~12 minutes to ~5 minutes.

### Changes 🏗️

- Inject build cache config into docker compose config; let `buildx
bake` use GHA cache directly
  - Add `docker-ci-fix-compose-build-cache.py` script
- Optimize `backend/Dockerfile` + root `.dockerignore`
- Replace broken DIY pnpm store caching with `actions/setup-node`
built-in cache management
- Add caching for test seed data created in DB

### Checklist 📋
