Add empty states for show relations

[Bonapara]

Current Behavior

1. There is a strange feeling of emptiness (no empty state).
2. There is a strange horizontal bar
3. We display "All(0)" even when there are no records.

Desired Behavior

For 1. and 2. if an object has no associated relations, display a placeholder like this: For 3. don't display "All(0)" when there is no associated records

Thanks @jeet1desai 🙏

I didn't mention it, but the icons for the empty state represent the related object, such as 🎯 for opportunities. Also, display the singular name of the object in the empty state, like "no opportunity" instead of "no opportunities."
