Set user's 24h preference from their current OS locale (#29651)

Fixes: https://github.com/go-gitea/gitea/issues/28371

Fixed by using a JS solution that formats according to `lang`, but alters the 24h format setting as per user's locale. This will work for all tooltips:

I think there is only one other place in the UI where we render such absolute dates, which is in the actions view and which I've also fixed:
