util: add TransactionError includes and namespace declarations

Add TransactionError to node namespace and include it directly instead of
relying on indirect include through common/messages.h

This is a followup to a previous commit which moved the TransactionError enum.
These changes were done in a separate followup just to keep the previous commit
more minimal and easy to review.
