Moderation notifications (Get notified when you've been banned, your post has been removed, etc)

[dessalines]

Requirements

• Is this a feature request? For questions or discussions use https://lemmy.ml/c/lemmy_support
• Did you check to see if this issue already exists?
• Is this only a feature request? Do not put multiple feature requests in one issue.
• Is this a backend issue? Use the lemmy-ui repo for UI / frontend issues.
• Do you agree to follow the rules in our Code of Conduct? #4697

Is your proposal related to a problem?

Currently, there are no notifications to your inbox when any moderation action is taken on you. These could include things like:

• You've been banned from a community.
• Your post / comment has been removed / restored.
• Your post has been stickied.

While it would be possible to add these to the inbox, we really need to first solve the SQL paging / filtering issue for multiple types: #2444

Otherwise we're multiplying the calls, rather than having a single unified one, that returns multiple types.

Describe the solution you'd like.

Get a notification when a moderation action has been done on your content.

Describe alternatives you've considered.
