this PR lays the foundations for #1213 and is on top of #1215.

• renames list_txsummaries -> list_value_transfers to avoid conflict with new transaction summaries interface
• creates to-be-used structs for displaying tx summaries to user
• creates unimplemented list_transactions fn and TransactionsCommand
• adds error type for production builders
• moves build macros to utils for use in production builders as well as mocks
