Andrew Stoltz d3ffad9190 fix(telephony): PiperUrl 10.0.57.15 → .17 + shared-tts hostPath for TTS playback ...

Piper was never reachable on 10.0.57.15 — edge1's actual address is
10.0.57.17 (SSH config, project_edge1_sdcard memory). Every telephony
prompt hit the 8s HttpClient timeout and fell back to the built-in sound
map (vm-advopts, vm-goodbye, beep) instead of speaking the real workflow
text. Verified from noc1: `curl http://10.0.57.17:8500/health` returns
HTTP 200 in 6ms, `POST /tts` returns a 16kHz mono WAV in 606ms.

Changes:

- apps/telephony/telephony.yaml
  - `Tts.PiperUrl` → `http://10.0.57.17:8500`
  - NetworkPolicy egress allow → `10.0.57.17/32:8500`
  - Header comment now documents the POST /tts {"text":"..."} contract
  - telephony-web pod mounts `/shared-tts` from hostPath `/tmp/tts-audio`
    (rke2-agent1). This is where `AsteriskProvider.SpeakTextAsync` writes
    the synthesized .sln16 before calling ARI `Play sound:tts/<name>`.

- apps/asterisk/deployment.yaml
  - Asterisk pod mounts the same hostPath at
    `/var/lib/asterisk/sounds/tts` so it can read and play what
    telephony-web wrote. Both deployments have
    `nodeSelector: kubernetes.io/hostname: rke2-agent1` so the hostPath
    is guaranteed to be the same directory.
