Remove social subscribers

[irfano]

Fixes #20714

This removes social subribers from the detail screen of the Total Followers card and additionally, changes the endpoint for the "Total Followers" card from /sites/$site/stats/summary/ → stats/subscribers.

Additionally, this PR removes FollowerTotalsUseCase, which was already unused. This card was being used only on the WordPress app but then we removed stats from WP, now it's fine to remove the usecase as well. I haven't removed InsightType.FOLLOWER_TOTALS from FLuxC for now because it may cause crashes on a case when upgraded from a very old version since selected insight cards are stored in the db.

Lgtm, works as expected 👍 I went ahead and merged in trunk since there was a conflict. Just curious, when would be considered a good time to remove InsightType.FOLLOWER_TOTALS from FluxC?

Thanks for resolving the conflict.

when would be considered a good time to remove InsightType.FOLLOWER_TOTALS from FluxC?

I've made a note of it for myself. I will remove it after the project by checking if it affects old versions.

Sounds good, thanks!
