Onboard QReader data loggers by mapping their values

The data logger wizard now onboards QReader loggers. On the "Map values" step you browse every raw value the device exposes and map each one to a known metric. The "Dry run" step then shows the exact metrics your mapping produces before you save. Only the values you map are collected.

• Values are grouped as on the device, with a live sample, and you can search and filter them.
• Each raw value maps to exactly one metric, and you can invert the sign per value.
• Unit prefixes such as kW and kWh are rescaled to base units automatically.
