Streamlining Flows Across Environments: Export, Import, and Duplicate Features

Summary Enable Export, Import, and Duplication of Flows in Directus for easier management across multiple environments and for prototyping. Basic Example _No response_ Motivation Managing Flows across multiple environments is cumbersome as it requires manual recreation. Additionally, experimenting with different versions of a Flow is challenging. The ability to export, import, and duplicate Flows would streamline these processes, making Directus more flexible and user-friendly. Detailed Design Export & Import: • Add "Export" and "Import" options in the Flow UI. • Exporting creates a JSON file containing the Flow configuration. • Importing allows a JSON file to be uploaded, recreating the Flow. Duplication: • Introduce a "Duplicate" option next to each Flow. • Clicking it creates a clone of the Flow in the same environment, appending "-copy" to the name. Requirements List Must Have: • Expo…
