Enable API-based impression tracking

[coderberry]

User Story

As a platform owner, I want to integrate directly with CodeFund via API in order to fetch the ad creative and display it natively.

Why Is this Needed?

This is a requirement for us to integrate with platforms in the future such as codesandbox.io, cmty.io and more.
