Background
The Activity Tab experiment ran for a limited time, and we already got the results back.
The feature is not being made permanent as is. The feature was developed with a different process, resulting in code we do not want to reuse in case we develop a permanent version.
Eng notes
Remove all Activity Tab V1 files, logic, and developer settings.
Test notes
- Older activity tab toggles shouldn't appear
- No changes to the new activity tab
