Fix database-integration-tests to run all database tests

Previously only ran test_graphiti_mock.py, now runs all database tests:
- tests/test_graphiti_mock.py
- tests/test_graphiti_int.py
- tests/test_node_int.py
- tests/test_edge_int.py
- tests/test_entity_exclusion_int.py
- tests/cross_encoder/test_bge_reranker_client_int.py
- tests/driver/test_falkordb_driver.py

The -m "not integration" filter excludes API integration tests that call
external services (Anthropic, OpenAI, etc).
