Reduce API result size

[de-code]

Currently the API returns full and redundant objects that may not be needed.
For example for every potential reviewer, their full manuscripts are returned which also include all of the authors and full person details - which are not used in the UI.

The same manuscript or person may be returned multiple times. The result could be greatly reduced by removing redundant information (e.g. include a person reference instead).

GraphQL may be a good candidate to use.
