fix: forward ONECLI_API_KEY to OneCLI SDK for authenticated container config

Ports the v1 fix from PR #1777 (originally 8b5b581 by @johnnyfish).
Cherry-pick did not apply cleanly because v2 reformatted the surrounding
code and split OneCLI usage into two sites — manual port was needed.

v2-specific adaptations:
- Also forward apiKey at the second OneCLI call site in
  src/modules/approvals/onecli-approvals.ts (v2 split the approvals
  module out of container-runner).
- Skipped the companion test-mock commit (38163bc) — it patches
  src/container-runner.test.ts, which no longer exists in v2 (tests
  consolidated into host-core.test.ts).
