ci(verify-pipeline): fix stale v1/ working-directory + SECRET_KEY env

Same drift as #559 but in CI: the workflow ran `working-directory: v1`
on the two verify steps, but the Python codebase moved to `archive/v1/`
ages ago. The job failed with:

  An error occurred trying to start process '/usr/bin/bash' with
  working directory '/home/runner/work/RuView/RuView/v1'.
  No such file or directory

Fixed both occurrences (working-directory: v1 -> working-directory:
archive/v1).

Also added `SECRET_KEY` env var to both steps — `verify.py` transitively
imports `src.app` -> `src.config.settings` (since PR #547 introduced
pydantic-settings with a required `secret_key` field). The value is
never used for any auth path in the proof pipeline; it just needs to
satisfy the import chain. Same env-var workaround used locally to make
`./verify` pass.

After this commit, "Verify Pipeline Determinism (3.11)" should go green
on this PR.
