feat(hogql): Format actors modal date labels

[webjunkie]

Problem

Actor modals just use date value and it could be nicer with a label

Changes

• use existing date label format function
• improve some types, we can pass datetime to the frontend as it is, it will be turned into JSON nicely

Does this work well for both Cloud and self-hosted?

It should

How did you test this code?

• checked tests and frontend

Looks good to me! 👍

Just a test that seems related is failing.
