Greptile Summary

This PR updates campus IG metrics and adds a detailed karma breakdown to user profiles. The main changes are:

• Counts active campus IG chapters directly.
• Splits approved karma into general, intern, IG, and event categories.
• Includes event and organizing-IG metadata in profile responses.
• Limits intern-role classification to active role links.

Confidence Score: 5/5

This looks safe to merge.

• The active-role filter fixes the reported historical-role misclassification.
• No separate production-breaking issue related to that role-state behavior remains in the updated code.
