fix: change typeid check to dynamic_cast (#1409)

This PR changes the way we check for compatibility in the `WhiteBoard` as sometimes the typeid check would fail, even if the cast would work.

The reason for the failure is not fully understood, but a `dynamic_cast` is ok in this case, as this is not a time-critical operation.
