fix: exclude tracked change metadata from explicit runProperties check

The DOCX converter stores paragraph-mark tracked changes (trackInsert,
trackDelete) inside runProperties. These are revision metadata, not font
overrides, but hasExplicitParagraphRunProperties counted them as explicit
formatting — blocking previousParagraphFont inheritance for list items
with tracked paragraph marks.

Filter out trackInsert/trackDelete keys before the check so only actual
formatting properties prevent font inheritance.
