fix: Recreate and upload all missing flow engine files

This commit provides a complete and clean implementation of the JSON-driven flow engine to resolve persistent issues with missing files in previous commits.

This commit includes:
- All individual flow definition files in the `talia_bot/data/flows/` directory.
- The `talia_bot/data/services.json` file.
- The `talia_bot/modules/flow_engine.py` module with corrected logic for handling user responses and robust role assignment.
- All other necessary backend modules that were missing after the environment reset.

This comprehensive commit ensures that all required files are present and correctly implemented, providing a stable foundation for the new modular conversational architecture. All code has been reviewed and corrected based on feedback.
