Use ISO 8601 date format

Explicitly specify the ISO 8601 format `Y-m-d H:i` in the date template.

Django 5.0.5 removed the USE_L10N setting making the locale-specific
formats override DATE_FORMAT and DATETIME_FORMAT. See
https://forum.djangoproject.com/t/datetime-format/30811/10 for details.

Fixes #520
