fix: correct withdrawal-review account lookup, switch tenant to utkarshbank

- Manager withdrawal-review screen always searched the Savings account
  type regardless of the request's actual account_type, so reviewing a
  Current-account withdrawal failed with "Account not found". Reuse the
  existing SEARCH_ACCOUNT_TYPE_TO_AC_TYP mapping (already used by the
  cashier lookup path) instead of a hardcoded 'SD'.
- Point the UI tenant id at utkarshbank (was lincpay) to match the new
  backend tenant.
