feat: add agent favorite functionality with UI and API implementation

- Add `addFavorite` and `removeFavorite` API functions in agent.js
- Implement favorite button UI in Agents.vue with star icons
- Add login check before favorite operations using token manager
- Sort agents with favorites appearing at the top of the list
- Include success/error messages for user feedback
- Add backend API endpoints for creating/deleting agent favorites
- Update agent list response to include favorite status
- Style favorite button with hover and active states
