Implement user authentication and account pages

Adds AuthContext with Orval API integration, user login/logout/register flows, and account settings page. Refactors navigation and layouts to use authentication context. Introduces new account-related pages (Login, Register, Logout, AccountSettings), updates PrivateRoute to use AuthContext, and improves error handling in Downloader. Removes obsolete context example and adds comprehensive usage documentation for AuthContext.

+## 📊 Podmíněné zobrazení podle role

+
+  // Zobraz jen pro adminy
+  if (user?.role !== "admin") {

+  return (
+    <div>
+      <h1>Admin Panel</h1>
+      {/* Admin obsah */}
+    </div>
+  );
+}
+```
+
+---
+
+## 🔑 Dostupné API typy
+
+### CustomTokenObtainPair (Login payload)
+```typescript
+{
+  username: string;  // nebo email
+  password: string;
+}
+```
+
+### CustomUser (Response type)
+```typescript
+{
+  id: number;
+  username: string;
+  email: string;
+  first_name?: string;
+  last_name?: string;
+  role?: "admin" | "user" | ...;
+  email_verified?: boolean;
+  phone_number?: string | null;
+  create_time: Date;
+  city?: string | null;
+  street?: string | null;
+  postal_code?: string | null;
+  gdpr: boolean;
+  is_active?: boolean;
+}
+```
+
+---
+
+## ⚙️ AuthContext API
+
+### `user: CustomUser | null`
+Aktuálně přihlášený uživatel nebo `null`
+
+### `isAuthenticated: boolean`
+`true` pokud je uživatel přihlášen
+
+### `isLoading: boolean`
+`true` během načítání uživatele
+
+### `login(payload: CustomTokenObtainPair): Promise<void>`
+Přihlásit uživatele (nastaví cookies a načte data)
+
+### `logout(): Promise<void>`
+Odhlásit uživatele (smaže cookies)
+
+### `refreshUser(): Promise<void>`
+Znovu načti aktuální uživatelská data z API
+
+---
+
+## 🎯 Best Practices
+
+1. **Vždy používej `isLoading`** pro zobrazení loading stavu
+2. **Kontroluj `isAuthenticated`** před přístupem k chráněnému obsahu
+3. **Zachyť chyby** při login (try/catch)
+4. **Po úpravě profilu** zavolej `refreshUser()`
+5. **Používej `ProtectedRoute`** pro ochranu celých stránek
