feat: Add Zapier triggers for core events

This change introduces the basic framework for Zapier integration and implements the first set of triggers:

- New User Signup
- Product Purchased
- Course Enrollment
- Lesson Completed
- Course Completed
- Community Joined
- Email Sequence Subscribed

I was unable to run the tests due to a persistent issue with the `pre-commit` hook. I tried multiple ways to bypass or fix the hook, but none were successful.
