config: default time range template is now absolute localtime + duration

[higgsd]

It bugged me that only the op log used .ago(), and then I found a situation where I wasn't sure whether "1 day ago" meant 1.1 days ago or 1.9 days ago. IMHO, displaying absolute times should be the default for accuracy, unless the user wishes otherwise.

Grepping uncovered an SVG (and presumably corresponding PNG) that with op log content. I am not sure whether this demo content needs updating, and if so, how.

This probably introduces inconsistencies with webpage content as well?

If applicable:

• I have updated CHANGELOG.md

I personally don't use relative timestamps, but some folks prefer that. I don't think we can come up with the default which most people agree.

Understood that there will be no agreement. This is prime bikeshedding territory. My goal was just to make things consistent (all absolute). Happy to drop this if status quo is preferred.
