Refactor: Rename triggers to events in trigger-related entities and services

- Updated class and variable names from 'triggers' to 'events' across multiple files to improve clarity and consistency.
- Adjusted related data structures and methods to reflect the new naming convention, including changes in API entities, service methods, and trigger management logic.
- Ensured all references to triggers are replaced with events to align with the updated terminology.
