Multiple organizations with nested projects

[GerbenAxendo]

We manage multiple platforms for enterprise clients. Since these clients have different compliancy rules we have created different organizations in the portal. From these organizations, we invite the members, so we (or more specificaly: the client) has insight to all members (and their MFA setttings) in one view.

Unfortunately, it is not possible to also move the client projects "under" the organisation, since "the client (organization) would then be invoiced" (per helpdesk ticket #5478356) and also per: #706 (comment)

As a result: members can be invited by the client using the portal and the Umbraco back-office, but cannot be removed because client doesn't have access to project settings (Overview > team). This violates a number of (enterprise grade) compliance and GDPR rules.
