fix(scriberr): model caches on /tank; HF_TOKEN is a placeholder (no real credential)

Browse Source 
HF_HOME, TORCH_HOME and NLTK_DATA now point under /app/whisperx-env (the
/tank bind mount). Before, ~6 GB of models sat in the container layer and
every recreate threw them away. The cache was copied across (98/2/78 files,
apparent sizes identical).

HF_TOKEN is now a placeholder. Measured: with an invalid token, cached gated
pyannote models still load (huggingface_hub falls back to the cache on the 401),
and public models still download (HTTP 200). Scriberr only checks that the token
is non-empty. Re-verified on GPU 3: pyannote community-1 and WhisperX+3.1
diarization both exit 0 from the /tank cache with no downloads.

- **Diarization FIXED 2026-10-06 ~1320 (Prime: "whisper doesn't work at all, need diarized transcripts").** Three faults: no `HF_TOKEN` (pyannote is gated). FINAL: the gated models were downloaded once, caches moved to /tank (`HF_HOME`/`TORCH_HOME`/`NLTK_DATA` under `/app/whisperx-env`), and `HF_TOKEN` is a placeholder (Prime 1330: "move the downloads and drop the token"). Cached gated models load with an invalid token; a NEW gated model needs one download with vault `fv-ml1/hf-token`. torchcodec 0.16 in the pyannote env against torch 2.8 (`AudioDecoder` undefined; pinned to 0.7 by hand, durable as `patches/0003`, applied at the next rebuild); and the WhisperX adapter's CPU/small/float32 defaults.

- **URL is https://scriberr.nh3.phasefinal.com since 2026-10-01** (fronted by the fleet TLS caddy on nh3-dev; Caddyfile backup `.bak-20261001-scriberr`). Prime's "can't initialize recorder" was the SecureContext rule: `getUserMedia` is refused on http://. The HTTPS name is in `ALLOWED_ORIGINS` (`playbooks/scriberr-https-origin.yaml`); http://10.251.50.54:8080 still works except for recording. ⚠ `/opt/docker/compose/scriberr` is lkraven-owned, so `deploy-stack.sh` as infra-ops FAILS there (Permission denied); upload single files with `elway --upload --sudo --owner lkraven:lkraven`.
