feat(PE-5540): recursive state traversal endpoint

[dtfiedler]

This allows for traversing nested objects of contract states. It is a separate endpoint to make it clear it is traversing state of a contract. To avoid unbound recursion (specifically for unknown contracts that could have a gnarly state), we set the max depth of the path to 3 params.

Examples:
