feat(status-dashboard): register security guards in auth module

Update auth module to export new guards:
- FlexibleAuthGuard (multi-method authentication)
- VpnGuard (IP validation)
- AuthMethods decorator (per-endpoint configuration)

Makes guards available for dependency injection in controllers.
