Lead-quality gate: require a name or location, not just a reason

A call produced a near-empty lead (name=None, location=None, only reason="check
on my eyes"). Changed the extraction gate from "name OR reason" to "name OR
location" — a bare reason with no name and no office isn't an actionable
worklist card, so skip it. Verified: reason-only -> skip; name-only, location-
only, both -> keep.
