Still a working in progress.

You've made great progress on the Media Entity implementation here.

However, it looks like this issue was actually resolved and merged recently. The reason you likely didn't see it is that the existing implementation was placed in a different directory (nsc-events-nestjs/src/media/entities/media.entity.ts) than this PR.

Since the work is already in main, we should probably close this draft PR to avoid any merge conflicts or duplicate logic. Sorry about the overlap.
