fix(building-passport): don't cache property-meta fetch

getPropertyMeta self-fetched /api/property-meta with revalidate:60 (despite a
comment saying it shouldn't cache). Vercel's Data Cache served a stale response
from before the headline backfill, so the current EPC rating / SAP rendered
blank on the plans and plan-detail pages even though the API now returns them.
Use cache:"no-store" so backfilled headline values propagate immediately.
