Update app_spec.txt and coding_prompt.md for improved clarity and consistency

- Updated references to `app_spec.txt` and `feature_list.json` in app_spec.txt to include the correct path.
- Enhanced coding_prompt.md by incorporating testing utilities for better test management and readability.
- Added new utility functions in tests/utils.ts to streamline test interactions.

This commit aims to improve documentation accuracy and maintainability of testing practices.
