Do we need the "Video details" and the "Technical details" pages?

[oas777]

Everything that can be "done" (share) at

https://pr792.tobira.opencast.org/~manage/videos/O290gtPkcyw

can be "done" (better!) at

https://pr792.tobira.opencast.org/!v/O290gtPkcyw

and/or in the video editor (change metadata)

https://oc.tobira.ethz.ch/editor-ui/index.html?mediaPackageId=ad1890f6-07b9-4ad3-8346-60bef26e7a82.

And information from https://pr792.tobira.opencast.org/~manage/videos/O290gtPkcyw/technical-details can be added to the metadata.
