Introduces a full Palo Alto Prisma SD-WAN integration (dual-mode SASE
OAuth 2.0 / legacy CloudGenix auth, pagination, 429 backoff, session
priming) that surfaces per-path latency/jitter/loss/MOS, site
healthscore, link state, and alarm data for a store. Wired into the
/phonestatus WAN follow-up and eight new /voicediag WAN checks graded
against ITU-T G.114 / RFC 3550 defaults (env-overridable via
WAN_STANDARD_*).
Also adds a shape-aware detail renderer for /voicediag (per-link
tables with verdict icons instead of a stringified JSON dump) and a
--window flag (15m / 1h / 6h / 24h / 1d, env default via
WAN_STANDARD_WINDOW_MINUTES) so operators can widen the look-back
without redeploying. scripts/prismaProbe.js is bundled as a CLI for
schema iteration against a live tenant.
