Fix #31280

… charging

In BatteryHold mode, writing BatterySoCTargetMin = MaxSoc with strategy
Internal causes the inverter to charge the battery from the grid towards
MaxSoc when power_mng.use_grid_power_enable is true. Instead, read the
current SoC and use it as both min and max target so the inverter has no
incentive to charge or discharge.

Also explicitly disable use_grid_power_enable in BatteryHold and
BatteryNormal so the flag set by BatteryCharge doesn't persist and cause
unintended grid charging in subsequent modes.

Fixes #31280
