Implements Koring OIDC device-auth flow and integrates it into the app: core auth (TS/JS), IPC handlers, renderer API, KoringLogin React component, and a zustand koringAuth store. Handlers support device-code request, polling, refresh, get-user and logout and persist user info to existing auth/config. Also refactors many settings pages to use shared Setting components (SettingCard, SettingRow, SectionTitle, PageHeader) and replaces custom controls with @heroui/react primitives (Avatar, Button, Switch, RadioGroup, Slider, Input, TextArea, EmptyState). Adds OOBE login/welcome pages, a setting login route, installer header generator script, and a sample koring-auth.json for development.
