Subject: [PATCH] Fix water/gas total badge unit when sensor value is zero
 (#30279)

Fix water/gas badge when rate is 0

If there is only one flow rate sensor, and it has a value <=0, the badge would be displayed without a unit because the sensor gets skipped.

Instead of skipping <=0 values, continue to process sensor, but clamp the value to a minimum of 0. This ensures for single sensors we have a unit, and for multiple sensors the chosen unit is consistent even if the first sensor value drops to zero.
