tuya-convert container standard input not working correctly (Fix found)

OS: Pop!_OS 24.04 LTS x86_64

When running `docker compose up` for the containerized version of tuya-convert, the standard input is not fed correctly into the container. This makes the script unusable and after making the firmware backup it loops forever on the firmware selection prompt.

The naive fix that worked was suggested by chatgpt but i did not fully understand and test it.

It consists in modifying in the `docker-compose.yml` and adding two lines:

```
tuya:
...
stdin_open: true
tty: true
...
```

However that does duplicate the output of `docker compose up`.

I did use instead:
`docker compose up -d && docker attach tuya-convert-tuya-1` . In my case `tuya-convert-tuya-1` is the name of the container.

At the end it worked, however I am now pretty tired as it took various hours of trial and error.

Start with docker-compose.yml and reproduce the containerized flow using docker compose up, checking how standard input reaches the service. Confirm a fix lets the firmware selection prompt accept input without looping or duplicating output, then verify the documented docker compose invocation behaves as expected.
