feat: add ahoy analytics for event tracking

- Integrate Ahoy gem for tracking user events and visits
- Create models for Ahoy events and visits
- Implement admin interfaces for managing events and visits
- Add background job for cleaning up old analytics data
- Update application controller and other relevant controllers to track specific actions

This commit implements a comprehensive event tracking system that logs user interactions
within the application. Additionally, it includes mechanisms for managing and
cleaning historical visit and event data, ensuring efficient data handling.
