Neat dms connections reverse 003

Validates that source property for the reverse connections is a direct relation.

What it does

Checks that the property referenced in a reverse connection's 'through' clause is actually a direct connection property (not a primitive, edge, or reverse relation).

Why is this bad?

Reverse connections can only work with direct connection properties. Using other property types breaks the bidirectional relationship. Pointing through another reverse direct relation never resolves to container storage, even when containers have correct direct relation properties defined.

Example

If WindFarm has a reverse property turbines through WindTurbine.name, but name is a Text property (not a direct connection), the reverse connection is invalid. If ViewA's reverse property points through ViewB's reverse property instead of a direct relation, neither reverse connection maps down to a container.
