[docker] Use build for Cuebot in docker-compose for development

Update docker-compose.yml to build Cuebot from source by default instead
of using pre-built image. This ensures the latest code changes are
included in the container.

Add comments to explain when to use:
- build: Compile from source with latest code (recommended for
development)
- image: Pre-built image for faster startup (commented out)

This fixes issues where the client spec version is newer than the server
DTD version when using outdated pre-built images.
