refactor(cardinal)!: rename Transaction/TransactionType to Message/MessageType

[technicallyty]

NOTE

im going to leave the TransactionQueue as it is currently named. Would change it to MessageQueue if it only contained messages, but i believe Transaction takes precedence here

What is the purpose of the change

renames cardinal's Transaction types to Message.

Brief Changelog

Testing and Verifying

run cardinal unit tests.
