Deprecate:
* `path` and `url` of `ActorImage` (used to represent account/channel
avatars/banners) in favour of `fileUrl`
* `path` of `AvatarInfo` (used in notifications) in favour of `fileUrl`
* `captionPath` of `VideoCaption` in favour of `fileUrl`
* `storyboardPath` of `Storyboard` in favour of `fileUrl`
* testing not removing old file and adding columb to db
* implement feature
* remove unnecessary config changes
* use only keptOriginalFileName, change keptOriginalFileName to keptOriginalFilename for consistency with with videoFile table, slight refactor with basename()
* save original video files to dedicated directory original-video-files
* begin implementing object storage (bucket) support
