[chore] warning doesn't say which sensor is stalled

[swingerman]

I had a Quick Look through the commit and I couldn't see if the logging will include information about which entity is causing the issue in the log, i.e:

01.194 WARNING (MainThread) [custom_components.dual_smart_thermostat.climate] Sensor is stalled, call the emergency stop

This doesn't say which sensor is stalled, and which entity the emergency stop has been called on.

I realise hvac_action_reason is set, but often this is empty by the time I want to look at it, which is why it would be good to log it so I can correlate it with an issue.
