fix(ui): show real battery charge/discharge/idle under watt-level solar control

FORK deviation from upstream: watt-level solar control keeps the battery
in HOLD mode (RS485 enabled) while actively charging/discharging, so the
mode-priority status and gauge mislabelled it "discharge locked".

- BatteryStatusCard.statusState: drop HOLD from the mode short-circuit so
  the status follows measured power; add an "idle" label for tiered-off
  units (0W) that previously showed nothing.
- SocGauge: drop HOLD from LOCKED_MODES and from the Pause-icon condition,
  so a discharging HOLD battery shows the arrow, not arrow+pause overlaid.

All deviations marked FORK; restore the HOLD lines to follow upstream.
