* Fix utility meter reset without tarrifs
When using a utility_meter helper set up with a "Meter reset cycle" of
"No cycle" it is impossible to properly reset the meter to 0 and utilize
the "last reset" and "last period" attributes on the helper.
With these changes the service call can now directly reset a meter in
such a configuration and the UI selector has been updated to include
utility meters in the selection list.
Fixes#96920
* Undo UI target selection modes
As requested to not cause confusion by being able to reset individual
meters when using multiple tariffs.
* Adjust logic to only reset standalone sensors
The original logic would allow resetting meters with multiple tariffs
which was an unintended side effect.
