refactor: Unified standalone image with both Neo4j and FalkorDB drivers

- Modified Dockerfile.standalone to install both neo4j and falkordb extras
- Both compose files now use the same standalone image
- Config file determines which database to connect to at runtime
- Added build-standalone.sh script for building and pushing to DockerHub
- Image tags: standalone, {version}-standalone, {version}-graphiti-{core}-standalone
