use ISO format for date/time range export in CSV

I could verify that currently (new) the export of date/time ranges looks like this:

2026-04-22T14:00:00.000Z -> 2026-04-22T15:00:00.000Z

with Capacities v1.62.2; none none; Mac OS v10.15.7; Safari v26.3 (WebKit v605.1.15); Desktop (Browser); 23.4.2026, 10:46:42; en (Europe/Vienna, UTC+2)

ISO 8602 defines not only the format of dates/times but also of ranges which is different:

https://en.wikipedia.org/wiki/ISO\_8601 / Time intervals:

Start and end, such as "2007-03-01T13:00:00Z/2008-05-11T15:30:00Z"

Capacities: 2026-04-22T14:00:00.000Z -> 2026-04-22T15:00:00.000Z

ISO: 2007-03-01T13:00:00Z/2008-05-11T15:30:00Z

So wouldn’t it be better to export date/time ranges in the ISO form which usesa "/" as separator and not „ -> „. ISO seems to be machine readable while capacities format looks more like readable as prosa for humans
