NdoleStudio/httpsms — reverse-engineered prompt

Build me a self hosted app that turns an Android phone into an SMS gateway I can control over a simple HTTP API. I want a small web dashboard where I can sign in, connect one or more Android phones, get an API key, see message history and delivery status, and configure things like webhook callbacks, rate limits, and message expiration. When I send a request to the API it should queue the message, notify the Android app, and have the phone send the SMS. When the phone receives an SMS, it should be able to forward that to my webhook.

Please include the Android app too, so it can link to my account, receive push notifications, fetch pending messages, send them through the phone, and report results back. If possible, support optional end to end encryption so message content is only readable on the phone.

Make it runnable locally with Docker and include enough setup docs so I can get it working. Look up current docs online if you need to.
