test: update fixtures to use real service host

- Add TEST_HOST config (default: 192.168.86.149) in conftest.py
- Update all test fixtures to use configurable host instead of
  docker hostnames (neo4j, qdrant, wiki, etc.)
- Fix test_integration.py WikiJS client to use username/password auth
- Fix ollama_client fixture to use ollama_embedding_model setting

This allows tests to run against real services from outside Docker.
