Get Most Active Users

Get the most active users in the past N days with a breakdown of what they did. Separates students and tutors.

Ranking prioritizes RETURNING users: active_days is the dominant scoring term, so a one-day burst can't outrank a genuine multi-day returner. Calls are split into "ChaCha Calls" (the ChaCha bot is a participant) and "Human Calls", and ChaCha "ghost" sessions (failed Gemini Live connects — empty transcript, fabricated ~300s duration) are excluded so per-user call counts/minutes reflect real usage.
