packetdial: build out + document the skill against the live NetSapiens v2 API

Key is now provisioned + live-verified, so grounded the skill in the real spec (RTFM):
- Mapped the OpenAPI surface (v44.4.10, 239 paths / 354 ops) — capability map added to
  SKILL.md (what the platform exposes vs what's wrapped vs raw-only).
- Added 6 live-verified read wrappers (ns.py + ns_client.py): callqueues, timeframes,
  sites, contacts, autoattendants, billing (domain limits/usage).
- Replaced the stale "not yet provisioned" credentials section with the live status
  (vaulted nsr_ reseller key, key-id nsr_hSGUB5Wo, scope Reseller 91912.service, RW) +
  the pbx.packetdial.com vs api.ucaasnetwork.com hostname note + override.
- api.md history updated. Writes remain gated behind --confirm; everything unwrapped
  reachable via `raw`.
