Reintroduce published flag for content groups, add live and remove single mode
The publishingMode NONE has been replaced with a separate flag. While technically, the mode is not relevant when a group is not published, with a separate flag the previous mode can be restored when toggling.
This partially reverts changes from 73da43b2077e8594c5ad400d78cc74854ab50d4f.
A new publishing mode LIVE
for live use cases has been added.
For non-live use cases, only publishing of all and and a range of
contents is relevant. For live use cases, Publishing of a range and
single publishing is relevant.
Furthermore, the SINGLE
mode has been removed. With the existence of
focus mode for rooms, it didn't not provide much value and added
complexity.
