feat: make home assistant add-on run optimization by default (#940)

When running as Home Assistant add-on the only viable usage is running with
cyclic optimization. Make this the default to als propvide a better experience
for first time users. The optimization will start with demo data, which also
helps to configure Akkudoktor-EOS to the personal usage.

The disabling of the automatic energy management is now an explicit mode
"DISABLED".
