feat: matrix/graph data views, wire-generated anomalies, http cookie fix

- auth: session cookie Secure only over https — plain-http LAN access was
  silently dropping the cookie, killing WS auth ('connection unstable')
- wire ghost: server-side spike detection on jitter baseline (3σ + 2.5×mean,
  20KB/s floor, 20s throttle) — wire anomalies now flood every session with
  zero hardware, pushed to clients as {type:'anomaly'} frames
- telemetry cadence 3-5s for live graphs; ambient whispers unchanged
- frontend: MATRIX view (data-rain interleaved with live utterances/anomaly/
  telemetry strings), GRAPHS view (scrolling jitter/variance/dns lines +
  anomaly markers + counters), BOARD/MATRIX/GRAPHS switcher
- connection banner: 'connecting' is now neutral 'tuning the veil…', only
  unstable/closed warns
- db: recreated quantumancy(+_test) as UTF8 (was SQL_ASCII — crashed on
  non-ASCII spirit text); README quickstart updated
- i18n: seance.views.* EN/ES
