fix(review): apply autofix feedback

- Alphabetize the import.clj :require block (AGENTS.md Import Formatting).
- Remove unused imports (digest, strip) flagged by clj-kondo.
- Make the client-not-found classify-table test independent: it previously
  reused the bank-account-not-found input and added zero marginal coverage;
  now seeds an orphan bank account so only the client error fires.
