Add Celery dependencies and enhance bulk seeder

- Add Celery, Flower, and related dependencies to requirements.txt
- Update bulk_seeder.py with progress callback support for Celery integration
- Clean up finetuned model dependencies (now served through Ollama)
- Update setup_ollama.py for enhanced configuration
