- Added `previewConfigKey` metadata to multiple scripts including fetch-binary, fetch-html, fetch-http, fetch-rss-feed, fingerprint, get-secret, jsonata, ntfy, render-template, and send-email, improving configuration visibility. - Updated the `FieldHelp` and `ScriptCard` components to utilize the new preview configuration, enhancing the user interface for displaying script metadata. - Refactored `TriggerCard` and `WorkflowTestPanel` components to support expanded views, improving user interaction and accessibility of configuration details. - Enhanced the `WorkflowVisualEditor` to manage test panel visibility more effectively. This update improves the overall user experience by providing clearer context and configuration options for scripts and workflows.
