Add bilingual native_range and wildlife_value fields (DE/EN) to species

Migration 011 adds native_range_de, native_range_en, wildlife_value_de,
wildlife_value_en columns. Backend INSERT/UPDATE queries updated ($64→$68).
Frontend species and cultivar detail pages use pick_desc() for language selection.
