fix(combat): _choose_spell_action heal branch gates on spell range + line of effect - a touch-range Cure on a distant ally was rejected by _cast_spell (OUT OF RANGE / NO LINE OF EFFECT) and wasted the caster's whole turn; extracted the offensive branch's reach check as _spell_reaches and reused it (the duplicated below-half check in the branch was a no-op copy of _find_ally_needing_heal, dropped) + 3 policy tests
