feat: add treemap and punchcard heatmap to dashboard L1/L2 (#94)

Browse Source 
Treemap: rectangle area = transaction volume, color = SLA compliance
(green→red). Shows apps at L1, routes at L2. Click navigates deeper.

Punchcard heatmap: 7-day rolling weekday x 24-hour grid showing
transaction volume and error patterns. Two side-by-side views
(transactions + errors) reveal temporal clustering.

Backend: new GET /search/stats/punchcard endpoint aggregating
stats_1m_all/app by DOW x hour over rolling 7 days.
