Note

Low Risk
Documentation-only updates in translated MDX files; low risk aside from potential formatting/anchor inconsistencies in rendered docs.

Overview
Updates translated columns.mdx (es/fr/zh) to match the revised Columns intro wording and to document the Column sub-component with a new section and usage example.

Wraps the Properties heading in translated examples.mdx (es/fr/zh) in a <div id="properties"> anchor for consistent deep-linking, plus minor punctuation/typography fixes in French.
