- Move get_docker_paths() implementation from filter_plugins to module_utils
to make it reusable by filters and lookup plugins (single source of truth)
- Adapt filter_plugins/get_docker_paths.py to re-export the shared util
- Add new lookup plugin "database" resolving DB settings from applications config
- Fix unit test patching: patch module_utils.docker_paths_utils.get_entity_name
instead of filter module, because imports are now bound at util level
- Add comprehensive unit tests for database lookup covering all helper-variable cases
