Erich Blume ce59e9951b Fix frontmatter field name: date-modified -> modified
Quartz's CreatedModifiedDate plugin recognizes `modified`, `lastmod`,
`updated`, and `last-modified` — but not `date-modified`. The wrong
field name caused Quartz to fall through to filesystem timestamps
(UTC in Dagger), showing incorrect dates on the rendered site.
