Refactor YouTube Upload to Synchronous Feedback Flow #458
Description
Currently, when a user uploads a video, we cut the browser connection immediately and handle the actual YouTube upload in a background process.
The Problem
Since we close the connection early, if the background process fails (due to YouTube API limits or upload errors), the user has no idea. They think it succeeded, but the video never appears.
The Goal
We need to change this flow to keep the connection open until the upload is actually complete. We should keep the user waiting on the screen so we can:
- Confirm the upload really succeeded.
- Immediately inform them if it fails or is incomplete.
