feat(trigger): enhance plugin and trigger integration with updated naming conventions

- Refactored `PluginFetchDynamicSelectOptionsApi` to replace the `extra` argument with `credential_id`, improving clarity in dynamic option fetching.
- Updated `ProviderConfigEncrypter` to rename `mask_tool_credentials` to `mask_credentials` for consistency, and added a new method to maintain backward compatibility.
- Enhanced `PluginParameterService` to utilize `credential_id` for fetching subscriptions, improving the handling of trigger credentials.
- Adjusted various components and types in the frontend to replace `tool_name` with `trigger_name`, ensuring consistency across the application.
- Introduced `multiple` property in `TriggerParameter` to support multi-select functionality.

These changes improve the integration of triggers and plugins, enhance code clarity, and align naming conventions across the codebase.
