Clean up/rearrange achievement notifications in Reverb.
Legacy achievements use a custom system to display earned achievements in the bottom right of the screen. This now duplicates Reverb functionality and needs to be swapped out. Due to the fact that the achievements can be custom made by wiki administrators the image, title, and description can vary. So there is one generic "user-interest-achievement-earned" notification type that simply contains the HTML contents of the generated achievement. The minor limitation here is that we can customize the HTML of the achievement details, but can not replace the entirety of the Reverb notification block unless we revisit that in the future.
Timeline: There is no defined timeline for this yet.
Example: The original legacy HTML shoved right into the user note/description portion notification.
Example: Minor clean up and removal of redundant elements.
