Fix onboarding blockers: eager jiwer import, stale formula, wrong upgrade hints

The Homebrew formula's resource list predated `assembly eval`, so a brew
install was missing jiwer/pyannote (and packaging) — and wer.py's
module-scope `import jiwer` sat on every command's import path
(main.py -> commands/evaluate.py -> wer.py), so *every* invocation,
including --help and doctor, died with ModuleNotFoundError.

- wer.py: import jiwer lazily inside the scoring functions (mirrors
  der.py's lazy pyannote import); new test pins the CLI import chain
  free of the whole scoring stack (jiwer/rapidfuzz/pyannote/numpy/
  scipy/pandas/sklearn) in a fresh interpreter.
- Formula/assembly.rb: regenerate resources from uv.lock (19 missing:
  jiwer, rapidfuzz, the pyannote stack, numpy/scipy/pandas/scikit-learn,
  packaging, ...) and extend the brew test beyond --version: --help
  imports the full command tree, plus a direct probe of the lazily
  imported scoring deps.
- update_check.py: the pipx/uv upgrade hints used the console command
  (assembly), but pipx/uv track the distribution name — "pipx upgrade
  assembly" fails with "not installed". Now aai-cli.
- doctor/login: "rejected (HTTP 401)" now says 401/403 (is_auth_failure
  treats both as rejected; proxies often answer 403), and the
  ffmpeg/PortAudio fix hints are no longer Debian-only.
- README: signup link in Authentication, Python 3.12+ stated before the
  install commands (with a --python recovery hint), brew trust marked
  conditional, ffmpeg/PortAudio decoupled from plain transcribe, a
  warning that PyPI's assemblyai-cli is not this project, and
  `assembly stream --sample` as the no-mic streaming starter.
