Screen orientation changes for self-ordering IoT displays are now sent directly from the user interface instead of the server. This avoids connection issues where the backend could not reach the IoT box, helping display rotation changes apply reliably.

As we performed the screen orientation update request from the backend, IoT couldn't be reached. We now send the request from the JS.

Self-order kiosk setup now connects to IoT devices correctly when the database uses a secure HTTPS connection. This prevents connection errors during kiosk installation and helps keep setup reliable for users.

We were fetching through http, leading to errors when fetching from a https db. Now using `rpc` instead of `fetch` to request dynamically.
