Ensure route CreationTransaction correctly implements that of domain

[iamacook]

Summary

The route-level CreationTransaction entity does not currently correctly implement that of the domain, e.g. addresses are not 0x${string} but string. This adjusts it to extend the CreationTransaction of the domain, adjusting the types accordingly.

Note: the associated changes to the data decoded entities were required to appease TypeScript.

Changes

• Implement the domain-level CreationTransaction in the route-level entity
• Implement the domain-level DataDecoded in the route-level entity
• Implement the domain-level DataDecodedParameter in the route-level entity
