refactor(trigger): rename TriggerApiEntity to EventApiEntity and update related references

- Changed `TriggerApiEntity` to `EventApiEntity` in the trigger provider and subscription models to better reflect its purpose.
- Updated the description field type from `EventDescription` to `I18nObject` for improved consistency in event descriptions.
- Adjusted imports and references across multiple files to accommodate the renaming and type changes, ensuring proper functionality in trigger processing.
