refactor: move directory path logic to InternalConfig

- Add directory name constants (TEMPLATES_DIR_NAME, ANSIBLE_DIR_NAME, TOFU_DIR_NAME)
- Move directory path methods from EnvironmentContext to InternalConfig
- Update EnvironmentContext methods to delegate to InternalConfig
- Improves separation of concerns and maintainability
- All directory names now use constants instead of hardcoded strings
