Show clear yes or no for HVAC general info and hazards instead of NA

Users have reported that in the HVAC section, "general information AC and central heat" and "hazards" are reading "NA" when they should be a clear "yes" or "no" answer. Users want these fields to display the actual answer so the report accurately reflects what was inspected.

Why it matters: HVAC condition and hazards are critical for the 4-point report; showing NA when a yes/no was recorded is misleading for clients and underwriters.
