Refactor template automation models and add GitHub client implementation

- Updated models in `models.py` to enhance documentation and structure.
- Introduced `TemplateConfig` class to encapsulate PR and workflow configurations.
- Modified `TemplateManager` in `template_manager.py` to utilize the new `TemplateConfig` model.
- Implemented `GitHubClient` class in `github_client.py` for comprehensive GitHub API interactions, including repository creation, file management, and workflow triggering.
- Improved error handling and logging throughout the GitHub client methods.
