Fix hero card aspect ratio and add horoscope generation functionality

Introduce horoscope generation via OpenAI API, including new API endpoints and database schema. Adjust card components in `home.tsx` to use `aspect-[16/9]` for consistent image sizing, resolving previous height stretching issues. Update dependencies in `package.json`.
