Show technical value of entity state in history

[jorisrymenants]

On the frontend all states are translated and shown in a user friendly way. In automations the correct technical value of a state has to be used.
It would be usefull to have a switch on the history panel where you can set to show all states by thier technical value. That way you can look at the history to find the exact states that occur for a given entity and can be used in automations.
Currently the ony way to see the technical value of a state is in the developer tools, but this only shows the current state.

this should be a relatively small change, but helps the end user a lot to find the correct and possible state values.
