feat(shirabe): resolve phase-b PhpMixed conversion TODOs

Implement self-contained call sites that wrap/unwrap PhpMixed without
touching shim bodies: platform-override and authentication IndexMap to
PhpMixed conversions, and dev-package-name / version-alias sorts via
usort with strcmp/strnatcmp. Drop stale TODO comments where the
PhpMixed unwrap was already inlined.
