Reverts text→datetime change. Uses format:'Y-m-d' (date-only) so the
datepicker omits the time component. Strips HH:MM from all Italy demo
story dates for consistency with the new date-only format.

Montalcino demo story had end_date: 2025-09-06 matching its start date,
causing a '06 – 06 Sep' range display. Removed from both the live page
and the demo source.
Template: added guard so end_date equal to the start date never renders
as a range, even if it appears in frontmatter.
