Overview

Mixes the modules RubyCMS admin views rely on into the host app's ApplicationHelper:

* RubyUI            — Phlex::Kit, makes components callable as methods in ERB
                    (e.g. AdminPageHeader(...)); defined by ruby_ui:install
* CmsApplicationHelpers / ContentBlocksHelper — shipped by the gem

Pagy 43+ has no Pagy::Frontend; admin pagination uses Pagy::Offset in AdminPagination and RubyUI::DataTable components instead. Idempotent: only adds includes that are missing.
