fix(trigger): improve event retrieval handling in PluginTriggerProviderController

- Updated the `get_event` method to return `None` instead of raising a ValueError when an event is not found, enhancing error handling.
- Adjusted the `get_event_parameters` method to handle cases where the event may be `None`, returning an empty dictionary instead of causing an error.
- Improved type hinting for better clarity and type safety.
