Fix merge conflicts and resolve circular import issues

- Resolve conflict markers in logging_config.py, main.py, app.py
- Fix circular imports in story_writer services (image/audio/video generation)
  by using lazy imports for get_story_media_write_dir
- Restore clean versions of:
  - sif_agents.py
  - tenant_provider_config.py
  - personalization_service.py
  - huggingface_provider.py
  - main_text_generation.py
  - logger_utils.py
- Use setup_clean_logging() consistently across app.py and main.py
- Restore verbose_mode handling in start_alwrity_backend.py
