Link to input in message details

[supahgreg]

This PR makes the Input name in the Received by section of message details a link to the Input on the Inputs page (if the Input still exists).

Description

This PR introduces aupport for linking and jumping (once) directly to an EntityListItem within an EntityList, and then uses that to link to an input from the Received by section of message details.

The ReviewBot items are unrelated to the changes in this PR, so I've skipped addressing them (for now).

Motivation and Context

Currently the details section links to the receiving node, but not the corresponding input. Being able to directly jump from a message to the related input on the Inputs page eliminates several manual steps.

Closes #2829.

How Has This Been Tested?

Verified I can click the message details input name/link and get to the corresponding input on the Inputs page.

@supahgreg: Thanks a lot for this PR! What do you think of opening a dropdown when clicking on the input name instead, which offers a couple of options, e.g. including/excluding this input from the search, or jumping to the inputs page (as implemented in your PR)?

[supahgreg]

@dennisoelkers Sure, I'll look into that.

@supahgreg: We can also take it from here, if you do not have the time for it.
