Add resumable upload support for "Studio"

[Kinuseka]

Describe the current behavior

Solving this issue will solve instances that run on cloudflare proxy or increase stability by redoing failed chunk uploads

Steps to reproduce

1. Edit a video from Studio
2. Append a video from beggining/last
3. Observe that it does not have chunk upload but rather sent from only a single stream

Describe the expected behavior

Studio uploads should have the same behavior from uploading the video normally
