refactor: finalize standalone services cleanup

- Remove root pnpm-lock.yaml (stale monorepo lockfile)
- Rename root package from bete-monorepo to bete
- Clean up root scripts to use cd instead of pnpm --prefix
- Remove ignoreScripts/trustedDependencies from frontend package.json
- Optimize Dockerfiles with multi-stage builds and proper layer caching
- Update .dockerignore to exclude build artifacts
- Remove leftover pnpm test config file from frontend
