Support .mov for video upload

[mayinrain]

Describe the bug
When I upload a video with a .mov extension, the file is recognized as an image format.
To Reproduce
Steps to reproduce the behavior:

1. Go to http://localhost:5173/
2. Click on file uploader
3. Select a file with a .mov extension
4. The file is recognized as an img.

Screenshots of backend AND frontend terminal logs
I printed the Base64 of the file and found that the prefix is data:application/octet-stream, so it is recognized as an img.

Here is the corresponding code

Yeah, I would recommend converting .mov to .mp4 before uploading it.

We probably will support more video formats, but there's lots of different ones so that isn't the biggest focus at the moment.
