fix(graph_dbs): add missing status parameter to Neo4jCommunityGraphDB… (#1179)

fix(graph_dbs): add missing status parameter to Neo4jCommunityGraphDB.get_by_metadata

The get_by_metadata method in neo4j_community.py was missing the `status`
parameter that exists in the base class and other implementations (neo4j.py,
postgres.py). This caused "unexpected keyword argument 'status'" errors when
the search API tried to filter by status.

Changes:
- Add `user_name_flag: bool = True` parameter for consistency
- Add `status: str | None = None` parameter
- Add status filter logic in WHERE clause when status is provided
- Update log messages to include status parameter

Fixes search functionality when using Neo4j Community Edition backend.
