refactor(api): fix pyright check

- Replaced `is_editor` checks with `has_edit_permission` in `workflow_trigger.py` and `workflow.py` to enhance clarity and consistency in permission handling.
- Updated the rate limiter to use `datetime.now(UTC)` instead of `datetime.utcnow()` for accurate time handling.
- Added `__all__` declaration in `trigger/__init__.py` for better module export management.
- Initialized `debug_dispatched` variable in `trigger_processing_tasks.py` to ensure proper tracking during workflow dispatching.

These changes improve code readability and maintainability while ensuring correct permission checks and time management.
