feat(EG-444): improve user organization access

[zigtan]

This PR is an enhancement to the User API changes that introduces the OrganizationAccess metadata to efficiently return the User's current list of Organizations and Laboratories they have been granted access to.

This enhancement modifies the OrganizationAccess data structure to include the OrganizationUser Status and LaboratoryUser Status.

It also updates the edit-organization-user and edit-laboratory-user APIs to make use of the respective PlatformUserService functions:

• editExistingUserAccessToOrganization()
• editExistingUserAccessToLaboratory()

The updating of a User's OrganizationUser Status to Inactive does not cascade to update the associated Laboratories, as the intent of the Inactive status is meant to be a non-destructive way of disabling a user's access to an Organization. Once the User's OrganizationUser Status is updated to Active again, the existing Laboratories access should be immediately available to the User.

The deletion of a User's OrganizationUser record (i.e. using the remove-organization-user API) is intended to be destructive, and will cascade to remove the associated LaboratoryUser access mapping records.
