fix: EntitySelect not showing selected value in weather/processed CSS editors

After _populateWeatherSourceDropdown() and _populateProcessedSelectors()
create new EntitySelect instances, the subsequent .value = assignment on
the native <select> doesn't trigger _syncTrigger(), so the trigger
button still shows "—". Call .refresh() after setting the value.
