v0.6.1 — Battery folded into System

Live is now two cards: System and Performance.

The battery card repeated voltage and current, which the System readings already carried. Only the state-of-charge bar and health were unique — so the bar moves into System as its own tier below the power flow, health joins the quiet readings beside voltage and current, and the card goes.

Battery SOC is now deliberately absent from the readings list: the bar shows it, and repeating it there was the last duplication left after the merge.

The System card reads top to bottom as rate → flow → charge → readings.
