Add source to span details

[JamesNK]

Fixes #3711

While making other repository changes I noticed that the source was on the trace instead of span. Moved it, and added the UI to display a context section to span details. The new section includes the span's source (in .NET land, this is the activity source name such as Microsoft.AspNetCore or System.Net.Http), parent id and trace id.

I'm not really familiar with the code. But diff seems to do what the PR description says, and makes sense to me - whatever I could understand!

is there a reason these are hardcoded?

Are you asking why the names aren't in resource files for translation? None of the "known" property names in the details screens are translated because none of the properties that come from OTEL are translated.

Another example: https://github.com/dotnet/aspire/blob/7d5a03251a9e7e3099e87ee34c9499dde3095288/src/Aspire.Dashboard/Components/Controls/StructuredLogDetails.razor.cs#L53-L64

Cool, assuming that it is ready to merge once CI is green. Thanks!
