URLs for chats

[phwizard]

In old version (Ethora Web) we have unique URL for each chat room which allows to share them by simply copying from the browser:

In new beta currently that's not the case:

Please introduce the same functionality into new beta.

Note - sharing with previews

Let's ignore the existing 'short link' and 'preview' sharing service functionality from the old version.
This functionality allows to display chat preview in outside applications (e.g. when sharing Ethora based app chat link via WhatsApp or Slack - via eto.li users will see a link preview including a chat name). This is done via a special server rendering service.

In chat sharing modal in the new beta version we will use the same URL as in the browser for now.

I will create a separate ticket in backlog for us to work on creating a similar server rendering service as we had in the old version, but for normal URLs.
