fix: address review feedback for actions CLI module

Fix argument parsing bugs in the execute command where actionId at index 0
was incorrectly skipped when --instance was absent, and flag values matching
the actionId string were erroneously removed. Add --help support to the
execute command for CLI report generation. Add missing bin script and
cli-report.md for cli-module-actions. Add resolveAuth tests. Bump
backend-defaults changeset to minor for the security-relevant auth change.
Replace cross-fetch with native fetch in cli-module-auth to avoid punycode
deprecation warnings during CLI report generation.
