refactor: simplify Docker build setup

- Remove all simple Docker files (Dockerfile.simple, Dockerfile.simple-local, build-simple-docker.sh)
- Remove docker-compose.local.yml
- Update docker-compose.yml to use Dockerfile.local for builds
- Update build-local-docker.sh as the single build script
- Keep only multi-stage Dockerfile.local for comprehensive local builds
