refactor(trigger): rename trigger references to event for consistency

- Updated variable names and types from 'trigger' to 'event' across multiple files to enhance clarity and maintain consistency in the codebase.
- Adjusted related data structures and API responses to reflect the new naming convention.
- Improved type annotations and error handling in the workflow trigger run API and associated services.
