feature: Upload and update package api

[gilbert-sci]

Summary

Removes the ssh logins for deploying an app, as that is all handled by the device now.

Note: We are still waiting on the device PR, so you will need to wait to update your device to test this.

Testing

• Tested deploy with and without --package, worked

[maxhodak]

we should validate at the beginning of the build command that the user has all required external dependencies (i.e., docker, fpm?) and bail early if they're missing something

[gilbert-sci]

FPM is in the docker image, so it should just be docker.

I think this is already being done too:

def ensure_docker() -> bool:
    """Check that *docker* CLI and daemon are available.

    Prints user-friendly errors and returns ``False`` if Docker cannot be used –
    allowing the caller to abort early without raising.
    """
    if shutil.which("docker") is None:
        console.print(
            "[bold red]Error:[/bold red] Docker CLI not found. Please install Docker before running this command."
        )
        return False

    try:
        subprocess.run(
            ["docker", "info"],
            stdout=subprocess.DEVNULL,
            stderr=subprocess.DEVNULL,
            check=True,
        )
        return True
    except subprocess.CalledProcessError:
        console.print(
            "[bold red]Error:[/bold red] Docker daemon does not appear to be running. Please start Docker and try again."
        )
        return False
