Expand confusable pairs beyond -teen/-ty with oh/zero, a/eight, to/two, double-digit readbacks, and narrowband letter swaps. Treat confusable swaps as high-severity misheard_number and pin an account-number fixture. Fixes AgentPostmortem#4

Summary
Mis-hearing checks covered the classic -teen/-ty amount pairs, but the confusions that cost the most on a real phone line are digit and letter swaps on account numbers, card readbacks, and reference codes.
