fix: images are not included in PDF exports (#16076)

## Description

- This PR address issue https://github.com/twentyhq/twenty/issues/15998
- The issue was that images are stored as signed urls and the backend
signed these with JWT
- BlockNote `resolveFileUrl` uses a public CORS proxy that couldn’t
access authenticated/signed URLs
