Praxis CI a7f7c4e1cc feat(P02): SLICE-08 operator API cohort endpoints — auth-gated, k-anon
TASK-08-01: server/operator/cohort.py — GET /api/operator/cohort practice
  volume view (sessions_count, active_learners_count), k-anon display.
TASK-08-02: server/operator/mastery.py — GET /api/operator/mastery
  (gate_open_rate, median_mastery_score, rubric_criterion_means).
TASK-08-03: server/operator/failure_patterns.py — GET /api/operator/failure-patterns
  (failure_mode:*, branch:* metrics).
TASK-08-04: server/operator/credentials.py — GET /api/operator/credentials
  + POST /api/operator/credentials/{id}/revoke (VC management, D-057).
TASK-08-05: tests/test_operator_endpoints.py — 401/200/503, suppressed
  cells value=null, last_updated=max, revoke, no per-learner data (R-DASH-02).
server/operator/_common.py — shared Cell/PathView/ViewResponse models +
  all_recent_aggregates query + group_by_path helper.

All endpoints auth-gated via Depends(current_operator) (D-057). No PII
beyond aggregates (D-031, R-DASH-02).

"""GET /api/operator/cohort — practice volume view (TASK-08-01, D-053, D-057).
Auth-gated (Depends(current_operator)). Returns k-anonymized practice-volume
aggregates from cohort_aggregates: sessions_count + active_learners_count per
path. Suppressed cells have value=null + cell_suppressed=true; the frontend
renders \"— (<10 learners)\". No per-learner drill-down (R-DASH-02).
last_updated = max(updated_at) for freshness (REQ-NFR-DASH-02).
