feat: Integrate Gemini API for hints and quotes

- Added `gemini_service` to handle gemini api calls.
- Updated `core_logic` to calculate hint count and fetch AI hints.
- Updated `email_service` template to display new AI hints section and
  AI-generated quotes.
- added halo lib's animated spinners for enhanced CLI visuals.
