Money tracker: Knab CSV import, multi-bank linking, sum reconcile, history range

- Knab statement exports: per-account ids (knab:<account>:<Referentie>), routed by IBAN,
  transfers between own accounts merged into one tracker account are dropped (interest kept)
- Import: multiple files, hand-entered twins get the import id, hand entries equal to the
  sum of 2-3 payments within a day are replaced by them
- bank-link --bank revolut|abn|knab with per-bank default account; ASPSP notes printed
- bank-sync: longest history on an account first sync (--full to force), sum reconcile,
  per-session status so one bank failing does not mark the others
- Timeline: 1 year / 3 years / All history range
