Add species-level data fallback on cultivar detail page
When cultivar fields are empty, show species-level data as fallback with italic styling and a "~ species" indicator. Applied to: frost tolerance (from USDA zone), light requirement (inferred from plant layer), and climate card (drought tolerance, USDA hardiness zone). Includes a footer note explaining estimated values.
