[UX] Browser shortcut for logging in to a repository with admin ui

[kavics]

Pls check if this is already available! I'd like to have a browser shortcut for logging in to a specific repository. This would require the AdminUI application to be able to handle a target repository query parameter:

https://admin.test.sensenet.com?repoUrl=inmem-daily.test.sensenet.cloud

• parameter name: repoUrl
• precedence: if the user is already logged in to a different repository (according to a browser cookie or local storage), we have to switch to the one provided in the url
• ~https is not necessary, default is https~ moved to https://github.com/SenseNet/sn-client/issues/1428

currently we can use repoUrl query parameter with encoded repository url
