feat: eg-367 add edit organization user api

[zigtan]

This PR completed the CRUD management of OrganizationUser mappings with the addition of the POST /easy-genomics/organization/user/edit-organization-user API endpoint to update mapping details.

This API will allow the updating of a User within an Organization make their access 'Active' / 'Inactive', and set them as either an OrganizationAdmin or not with the following JSON payload.

e.g.

{
    "OrganizationId": "e576cd7b-b7e4-4c3c-a273-584b2b9f9313",
    "UserId": "28634573-6194-45b9-b260-e0f74145133d",
    "Status": "Active",
    "OrganizationAdmin": true
}
