Closes: #5134

Describe your changes

• Remove activity_count everywhere in FEM so user stats are no longer using /project_preferences for calculating classification count.
• Untangle the spaghetti code of UPP > YourStats MST files.
• Add a disposer function with autorun to Store.js so that UserPersonalization refreshes every time the project id changes. This ensures the YourStats component displays correct stats data if you keep the same tab open and switch between FEM projects.

How to Review

• View any project's classify page and YourStats total classification count should match the total classification count displayed on your stats and homepage.
• When you make a classification, the YourStats component should increment as expected.
• See more comments below about removing legacy code.
