Overview: dcsource service label not correctly displayed

[philipptrenz]

While testing different DC meter types for SmartShunts, I noticed that the native UI and WASM deviated for a com.victronenergy.dcsource service in Monitor Mode "AC Charger" (/Settings/MonitorMode set to -2):

WASM (displays the correct "AC Charger" label):

Native UI (displays the wrong "Generic source" label):

After restarting the native UI, it was displayed correctly. Therefore, I suspect that this could be caused by a race condition when reading /Settings/MonitorMode.

Also note that the native UI shows a "DC loads" tile while the WASM does not. The tile is also gone from the native UI after restarting it.

I noticed more wrong labels shown for these DC meter types:

• Wind charger
• Shaft generator
• Water generator

Could resolve this by getting some signal from the DC meter model when any meter type changes, and then updating the Overview page layout when this occurs.
