BUG: Workspaces are not created / deleted during user creation / deletion

[ahaeslich]

User workspaces are only created when the user logs in to the backend. For example, using the impersonation button after creating a new user leads to an endless redirect loop (/neos/login -> /neos -> /neos/content -> /neos/login ...). Essentially it's the same outcome as in #4401.

Additionally I also discovered that user workspaces are not deleted anymore.

Environment

- Flow: 9.0
- Neos: 9.0
- PHP: 8.2

yes i also noticed that in: #4566

the workspace zookeeper doesnt do a particular good job :P

We should consider if that expectation (workspace(s) created when user created) is necessary for something or just something we are used to.

Closing as part of #4566
