For demo purposes, we want to work with workspaceMember has a non-system
object, allowing it to be displayed on the product, to be added custom
fields etc.
It is something we may want to do later anyway.
This PR adds a bypassPermissionChecks on workspaceMember repository
calls. This does not provide more permissions than before for other
workspaces: workspaceMember being a system object, permissions are
already bypassed for this one. (Note that actions such inviting a new
workspaceMember, updating a workspaceMember are protected by a system
permission checked in the relevant places).
This work does **not** allow any workspace to switch their
workspaceMember object to non-system, the switch is still manual.
