feat(prompts): rename prompt modules for clarity and consistency

Rename base_prompt.py to teaching_assistant_prompt.py and lab_assistant_prompt.py to lab_automation_assistant_prompt.py to better reflect their purposes. Update all imports and references accordingly to maintain consistency across the codebase. This improves code readability and aligns naming with the actual functionality of each prompt module.
