allscenarios-linux-blueprint-dashboard.conf: Add MACs for Smart Panel blueprint

Smart Panel blueprint sensor and switch devices MAC addrsses have to be:
 - configured on devices so they communicate over BLE from known addresses
   that do not collide,
 - configured in Home Assistant so it knows where to connect to.

Addresses can be overriden in local.conf of Linux build or in command line.
