Lock all nodes of the street

When studying a tree with multiple sizings, it would be very useful to have a way to lock all nodes on the current street.

At the moment, “Lock all previous nodes” only locks the path leading to the selected node. Applying a nodelock to one branch can therefore cause the solver to adjust sibling nodes and alternative sizings on that same street.

This is particularly relevant on the river, where nodelocks with multiple sizes are commonly used. It makes it difficult to isolate and study the effect of one locked action without manually locking every other river branch first.

A “Lock all nodes on the current street” option, which automatically locks every node and alternative sizing on that street before applying the nodelock, would make river nodelock work much more practical and controlled.
