apache/dolphinscheduler ? reverse-engineered prompt

Build me a modern workflow orchestration platform for data pipelines, something like DolphinScheduler, where people can create and manage complex jobs with a simple web interface. I want a drag and drop workflow builder, support for task dependencies, workflow versioning, pausing, stopping, recovering, and a clear way to see workflow and task status at a glance. It should also have a dashboard for monitoring workers, masters, and database health, plus support for multiple data sources like MySQL, PostgreSQL, Hive, and Trino.

Please include a backend and a web UI, with an API so workflows can also be managed from scripts or other tools. If it makes sense, add role based permissions, multi tenant support, and a clean setup that can run locally and be deployed in a few different ways, like standalone, Docker, or Kubernetes. Use current docs online if you need to.
