New endpoint: GET /api/events/call_monitor (upgrade to WS).
Per-subscriber writer queue, lazy ticker (250ms when active / 2s idle)
that only runs while >=1 subscriber is connected. Snapshot on connect
(KPIs + last 100 calls + watermark), deltas after (id > watermark).
Client may send {watermark: N} to resume.
