Fix non-reuse of the service name and allow user to specify their own name

[Xavinooo]

Proposed change

The service name assigned by this integration and stored in a file corresponds to the hostname. However, the integration does not retrieve it from the previously saved file on reload or restart.

When running Home Assistant in a Docker container without setting a fixed hostname, users must re-authenticate with the Freebox each time the container is recreated. This process requires pressing a physical button on the device to grant authorization. This PR resolves the issue.

Additionally, when adding a new Freebox, users now have the option to specify a custom name instead of using the hostname.

When adding the integration :

When validating on the device :
