feat(trigger): enhance trigger subscription handling with credential support

- Added `credentials` and `credential_type` parameters to various methods in `PluginTriggerManager`, `PluginTriggerProviderController`, and `TriggerManager` to support improved credential management for trigger subscriptions.
- Updated the `Subscription` model to include `parameters` for better subscription data handling.
- Refactored related services to accommodate the new credential handling, ensuring consistency across the trigger workflow.
