Faze 0A: battery guard carve-out — neblokovat import na nabiti pri zaporne cene

Browse Source 
_apply_export_plan_guard / _build_setpoints: kdyz slot CHARGE / importuje na
nabiti baterie (grid_sp>0 & bat>0), guard vrati sp beze zmeny a export_ban se
nenastavi. Opravuje, ze se baterie nedobila v zapornych cenach (CHARGE+17kW
prekloplen na PASSIVE -> Deye nenabijel ze site). Diagnoza: agent a599eecc.
