feat(trigger): integrate plugin icon retrieval into trigger provider

- Added `get_plugin_icon_url` method in `PluginService` to fetch plugin icons.
- Updated `PluginTriggerProviderController` to use the new method for icon handling.
- Refactored `ToolTransformService` to utilize `PluginService` for consistent icon URL generation.

This enhances the trigger provider's ability to manage plugin icons effectively.
