Zip Media Files for Easy Download

[pulgamecanica]

📦 Description

Instead of returning presigned URLs for each video, zip all media files into a single archive and provide a download link. This improves usability by allowing users to download all videos at once.

✍ Tasks

• Add functionality to create a ZIP archive of the extracted videos in video_extractor.py.
• Upload the ZIP archive to S3 and return a presigned URL for the ZIP file.
• Ensure the ZIP archive is removed after upload to save space.

🎯 Acceptance Criteria

• A single ZIP archive containing all media files is created and uploaded to S3.
• API response includes a presigned URL for the ZIP archive.
• Add a thorough documentation about the POST /extract endpoint response.

@pulgamecanica this sounds good to me, obviously we only need to zip it if its more than 1 video. Otherwise the ACs look good to me 🚀
