Fix issues with bosch alarm dhcp discovery (#145034)

* fix issues with checking mac address for panels added manually

* add test

* don't allow discovery to pick up a host twice

* make sure we validate tests without a mac address

* check entry is loaded

* Update config_flow.py

* apply changes from review

* assert unique id

* assert unique id
