Unify with the event detail header so that is contains also the name of the day

Should we extend the header with zero time as well (it's already present i the lower part, but to stay consistent with the header) ?

I don't think we should unify the date format on the event detail page for several reasons.

First, this information is already presented on the Info tab. Additionally, the event detail page already displays the actual start times, so showing the date relative to Start 0 doesn't add much value in this context.

More importantly, we should keep the UI as clean and readable as possible by displaying only the essential information. On mobile devices, using the longer unified format means the date and location will no longer fit on a single line and will always wrap into two lines. This reduces the available vertical space for the results, which is more valuable than displaying additional date information. With the current format, shorter location names still allow both the date and location to fit on a single line: https://orienteerfeed.com/events/cmr81qokx000u07mpkkycb3fh?tab=info
