Addons: prepare Proxito and dashboard to enable them by default

[humitos]

Prepare Proxito's code and dashboard to enable addons by default starting on October 7th, as planned:
https://about.readthedocs.com/blog/2024/07/addons-by-default/

• Removes the "Enabled" checkbox from the dashboard. All the addons will be enabled by default. Users will be able to disable each of them one by one, tho
• Always inject the HTTP header that tells Cloudflare to inject our JavaScript ¹

Note this code is temporary and can be deployed before reaching that particular date. The idea is to remove this code once this behavior becomes the default.

1. we will eventually remove this header and always inject our files. ↩

Makes sense. I do wonder if we keep the ability to disable Addons if someone wants, and then we don't inject them at all? I can see some folks wanting that, especially on Business.

This is a good point. I would probably only allow this on Business. I think we don't want OSS project without addons.

Currently, they can disable all the addons one by one, but we will still inject our JS and run our code -- even if we don't show any of them. I understand there would be specific cases where the customer doesn't want that, right?

[ericholscher]

Yea, it seems useful to at least have the option to not inject anything, since that might be useful in a few different contexts.

I updated this PR to keep the ability to disable addons on "for Business".

We will require to create AddonsConfig object for all the projects on Oct 7th. Something like should be enough, I guess:

for project_slug in Project.objects.values_list("slug", flat=True):
  AddonsConfig.objects.get_or_create(project__slug=project_slug)

[ericholscher]

Looks good.. I wonder about having the AddonsConfig.objects.get_or_create(project=project) code run somewhere in the codebase on that day automatically? Putting it in the Addons middleware is probably too heavy, but could be an option so we don't need to remember to run this on the CLI manually?

He, this was my first option as well; but I revert it because of the same reason.

I can write a Celery task to be run on that specific date automatically.

Hrm... it seems the crontab doesn't accept day, month, year... tho.

So, on October 7th we need to do the following things in both platforms (also local development):

1. Mark Default all past projects to True on DISABLE_SPHINX_MANIPULATION feature flag.
2. Run the following snippet to create AddonsConfig for all the projects:

   for project_slug in Project.objects.values_list("slug", flat=True).order_by("pk").iterator():
      AddonsConfig.objects.get_or_create(project__slug=project_slug)

3. Enable addons on all the project that disable it (community only)

   if not settings.RTD_ALLOW_ORGANIZATIONS:
       for addons in AddonsConfig.objects.filter(enabled=False):
           addons.enabled = True
           addons.save()

For now... I added a reminder in Slack at least 🙃

I re-reviewed this PR to check that everything was OK, and we are ready to merge it 👍🏼
