feat: add createdAt and createdBy to project

[shubhindia]

Motivation

Right now there is no info for the project about when it was created and who created it. We are developing some internal APIs to manage nobl9, and would love to get this info added.

Summary

I have added relevant fields to the Project struct, the core controller needs to populate these fields, but since it isn't open-source, I can't do that myself. @nieomylnieja Let me know your thoughts 😄

Release Notes

Added createdAt and createdBy fields to nobl9 project.
