Money transfer saga

The Flow checks the source balance, creates debit and credit memos, and moves funds. Each external operation has an Execute retry policy and proceeds to the Compensate Step after exhausting retries.

Steps are plain Python objects wired together in MoneyTransferFlow.__init__. They are constructed back to front so every Step can hold a typed reference to the one that follows it.
