Fix bin/ci: rubocop trailing blank line and brakeman fingerprint refresh

- Drop the extra blank line at end of shops_controller_test.rb class body
  (Layout/EmptyLinesAroundClassBody, leftover from Step 7 reset action removal)
- Refresh brakeman.ignore: AccountsShopkeeper::ROLES collapse changed the
  expanded permit() literal, so the warning fingerprint shifted. Same
  intentional rationale (admin-gated role assignment); only the resolved
  role list and fingerprint differ.
