The list button was registered by reassigning
frappe.listview_settings['Customer'] in a globally-loaded script, but
ERPNext's own Customer list_js (loaded when the list opens) overwrote it,
so the button never appeared. Register it via doctype_list_js instead —
which Frappe appends after the doctype's own list_js — and merge into the
existing settings (wrapping onload, preserving ERPNext's add_fields)
rather than reassigning. The form button and shared ns_statements helpers
stay in customer_statements.js.
