Platform admin entity with fields to lookup account managed resources

[techsmyth]

Description

As a platform admin I want to be able to see all entities that I need to manage

Acceptance criteria

• [ ] admin entity under platform with fields to return a) all spaces b) all virtual contributors c) all innovation packs d) all innovation hubs
• [ ] client admin queries updated to use these new fields instead of top level queries

Additional Context

Avoids the case whereby different admins see different data by giving an explicit route in for all admin queries.

TBD: how to deal with pagination in the api? TBD: what top level queries to be removed?

Areas that will be affected

To be added during the refinement
