Add int ids back in the info tabs until they are fully phased out

[jemayn]

I find myself missing the int ids several times a day after working on Umbraco 16.

They seem to have been removed in all major info sections:
Media:

Content:

However, the int ids are still the primary id some places and it makes it really annoying to work with this!

Some examples:

• Examine dashboard - it is the primary id in the listing - additionally if you just copy/paste the key into the searchfield it will not find the node. You have to write for example __Key:04bdf22a-5d72-42d1-9735-07483686210c to get it.
• Relations service still uses int ids for the child/parent relation entity:
  
• I don't have an example at hand, but have seen Umbraco Deploy error messages with an int id and a name of a content node

I'd expect there to be other places where the int id is still the primary one. I understand why you would remove it with the idea of going towards guid ids instead, but untill that has been done everywhere it makes it a pain to work with without having an easy way to find nodes based on int ids!
