Review Comment:
There isn't any join or additional things done to the `get_dag_runs`
endpoint. So basically listing dag_runs with `limit=1` and order by descending
start date should yield something really similar.
If you want to change the serializer for response to a more minimal stuff,
we can duplicate the endpoint to UI and do that. Or even better, figure a way
to request 'minimal' representation when requesting the API for instance all
endpoints could accept a `details=False` and get a minimal response if
specified. Buts that's a more global reflexion and might need some thoughts on
how to achieve that properly.
Also having a dedicated endpoint to fetch the `last` resource only seems
weird. I don't see how different it is from listing with limit 1 and a specific
order.

Review Comment:
Also we're missing the permissions check on the readable runs.
