feat(01-03): implement PIN auth routes, JWT HS256 enforcement, and auth tests
- Add auth HTTP handlers (login, me, logout) with proper JSON responses - Enforce HS256 via jwt.WithValidMethods to prevent algorithm confusion attacks - Add context helpers for extracting operator ID and role from JWT claims - Add comprehensive auth test suite (11 unit tests + 6 integration tests) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
