FarmBot/farmbot-web-app — reverse-engineered prompt

Build me a self hosted web app for managing a FarmBot from a browser or phone. I want users to be able to create an account, sign in, set up their FarmBot, design the garden layout, save plants and farm data, and create step by step movement or watering sequences that can be sent to the device.

The app should have a clean web interface plus a JSON API so other tools can connect to it. It also needs real time communication between the browser and the FarmBot device, so commands and status updates happen quickly. Include the server side pieces, database storage, authentication, environment configuration, and a Docker friendly setup for local development or deployment.

Please make it practical for developers to run locally, with sample env settings, setup instructions, and basic tests. Look up the current FarmBot developer docs online if you need to match their API concepts.
