Description

To close the milestone "API responses refactor" this PR removes some obsolete code in the back end and the front end.

(a) In the back end the following endpoints have been deleted:

• GET /video/ (replaced by GET /polls/{name}/recommendations/)
• GET /video/{video_id} (replaced by GET /polls/{name}/entities/{uid})

According to our logs, the only 3 requests to GET /video/ during the last 30 days have been made by robots.

# use the following query in Grafana
{filename="/var/log/nginx/json_access.log"} | json | http_host = "api.tournesol.app" | request_uri = "/video/" | request_method = "GET"

(b) In the front end the CriteriaRadarChart has been removed. This component is unused and depends on the deleted back end serializer VideoSerializerWithCriteria.

It looks good to me.

But a call to GET /video/ persists in "data-visualisation":

tournesol/data-visualization/utils.py

Lines 84 to 86 in ce94b0b

	response = requests.get(
	f"https://api.tournesol.app/video/?limit=99999&unsafe=true"
	).json()

So we may want to update that first (and trying to load all videos in a single request is probably no longer a good idea).

I think this can be removed now than only POST are supported by this route.

Exactly. I created the PR #1969 to address this point.
