chore(frank-tts): repoint narrator slots to the live voice packs

Frank replaced the narrator1/2/3 packs with cloned character voices
(wilwheaton, vaati, dr.kern, garrickhagon, jeffhays). The three narrator
slots are now carried by real packs: narrator1=wilwheaton, narrator2=vaati,
narrator3=dr.kern.

- frank-tts.env DEFAULT_VOICE narrator1 -> wilwheaton (a voice-less request
  400'd on the dead name; wilwheaton is narrator1's successor).
- Docs: correct the /health census and the podcast-speaker references in
  Frank TTS.md and Open Notebook.md to the live packs. Dated 2026-10-18/19
  measurement logs are left as history.

Open Notebook's live dank-duo speaker profile was repointed over REST
(Frank->wilwheaton, Comrade->vaati) - app-side, not in this commit.
Bats fixtures keep narrator1 as a self-contained sample pack; untouched.
