/**
 * Application root component.
 *
 * Wraps the entire application in:
 *  1. `FluentProvider` — supplies the Fluent UI theme and design tokens.
 *  2. `BrowserRouter` — enables client-side routing via React Router.
 *  3. `AuthProvider` — manages session state and exposes `useAuth()`.
 *
 * Routes:
 *  - `/setup`           — first-run setup wizard (always accessible; redirects to /login if already done)
 *  - `/login`           — master password login (redirects to /setup if not done)
 *  - `/`                — dashboard (protected, inside MainLayout)
 *  - `/map`             — world map (protected)
 *  - `/jails`           — jail list (protected)
 *  - `/jails/:name`     — jail detail (protected)
 *  - `/config`          — configuration editor (protected)
 *  - `/history`         — event history (protected)
 *  - `/blocklists`      — blocklist management (protected)
 *  All unmatched paths redirect to `/`.
