[PROD] Situation report list order

[szabozoltan69]

Issue

Recently it is not possible to set a situation report order, situation reports show randomly on emergency pages.
We should use an &ordering=created_at part in the request.

Details:

From backend side it would be possible to order by created_at and name:
https://github.com/IFRCGo/go-api/blob/develop/api/drf_views.py#L782-L784
But the client does not send any of them.
E.g.
https://go.ifrc.org/emergencies/6700/reports :
https://goadmin.ifrc.org/api/v2/situation_report/?event=6700&limit=9999
gives this order:
Middle East Complex Emergency - SITREP N.2
Middle East Complex Emergency - SITREP N.10
Middle East Complex Emergency - SITREP N.13
Middle East Complex Emergency - SITREP N.1
Middle East Complex Emergency - SITREP N.4
This is not date neither name order.

If we insert an
&ordering=created_at

• then it gives nice ordering.
  https://goadmin.ifrc.org/api/v2/situation_report/?event=6700&ordering=created_at&limit=9999

If a more sophisticated version is needed, we can insert a "position" or "order" integer to expicitely being able to define ordering.

Also on backend side Admin it would be nice to – at least – see created_at, because recently it can not be seen anywhere, just in the database.

Could be solved on backend side via IFRCGo/go-api#2275

You can test it on Staging, e.g. on https://go-stage.ifrc.org/emergencies/6700/reports
