base-config structure is changed (#618)

refactor(docker): restructure docker-compose for modular configuration

- Added reusable base configuration block (x-base-config) for ports, environment variables, volumes, deployment resources, restart policy, and health check.
- Updated services to include base configuration directly using `<<: *base-config` syntax.
- Removed redundant `base-config` service definition.
