Use `dagversion.created_at` instead of `dagversion.id` in UI

[jedcunningham]

Body

Instead of showing the id of dag version, which is an auto incrementing int, let's show the created_at datetime instead. This provides more value to users than an arbitrary incrementing counter.

e.g. "2025-03-25 19:05:01" and "2025-03-03 16:12:09" is way more useful than "v1" and "v2".

From a priority perspective, "v1" "v2" etc. is going to cause confusion and it really should be changed to something else. Timestamp is better, but since the uuid exists as the dag version id, the easiest may be to just show that (making it a UI only change!)

[jedcunningham]

I'd be much much happier with timestamp - it provides some context to the user. uuid is almost worse - it's also meaningless, but isn't obviously sorted like the autoincrement int :)

#48509 seems to be a related PR to this issue that changed the value to uuid .

Should we close this now, as the PR is merged?

[cmarteepants]

@dstandish do you know if anything is outstanding for this one? If yes, then yes let's close it.

[cmarteepants]

@phanikumv can't close it, I believe that only the backend was done. In main, "v1" is still everywhere

@bbovenzi could you please fix the UI part?
