* refactor: simplify reviewer token wiring; fix push re-scope + red test
- Remove the redundant _check_or_recreate_sandbox_for_proxy /
_refresh_github_proxy_or_recreate_for_proxy wrappers and call the
underlying functions directly (they already default the token to None).
- process_github_push_event: re-scope the GitHub App token when the push
payload lacked repo privacy/id but PR metadata reveals a public repo, so
reviewer.py never proxies a full-installation token for a public PR.
- Clarify the two-token sequence in trigger_pr_review_from_ref.
- Fix pre-existing failing test test_proxy_refresh_failure_recreates_sandbox
and add coverage for _reviewer_token_for_repo + push-event scoping.
