Improve `Video` AP compatibility

Compat with text/html descriptions
Compat with SPDX for licences
Compat with missing sensitive attribute
Compat with missing tag attribute
Compat with missing video file magnet URI
Compat with missing streaming playlist segmentsSha256Url
Compat with optional comments/likes/dislikes/shares URI in video object

Add more debug logs when the object is not valid
