Fix Claude OAuth token env for Actions (#1202)

## Summary
- pass `CLAUDE_CODE_OAUTH_TOKEN` through the Claude action step `env` as
well as the existing `with:` input
- keep OAuth token wiring consistent for Claude review and `@claude`
workflows

## Why
`anthropics/claude-code-action@v1` can resolve the OAuth input empty in
this runner path unless the token is also available in the inherited
step env. This matches the Hichee fix proven by shakacode/hichee#9633.

## Verification
- workflow-only YAML patch generated from the org Claude integration
audit

token in an additional supported way.

features.
