CKEditor 5 saves a data-list-item-id attribute on every list item, which
it only needs inside the editor; it bloated the frontend HTML and the RTE
content the API and the content feed hand to MyE&P. Both RTE presets now
import ep_theme's Processing.yaml, which removes the attribute on the way
into the database (exitHTMLparser_db); everything else passes unchanged.
Content saved since the go-live is cleaned once by hand after the
deploy (.ddev/plans/sql/2026-10-26-rte-list-item-ids.sql).
Checked locally as an editor: an RTE field with list item ids is stored
without them, other attributes (class on li, data-* on links) stay;
without the change the ids are stored.
