Read the orders that bill the app's subscriptions

$user->appOrders() and app(AnikeenId::class)->appOrders() read
v1/client/orders with the app's own token (scope orders:client):
all(), pending() and find(), paginated transparently, user scoped
when called on a billable.

-- Add `SocialiteProviders\Manager\SocialiteWasCalled` event to your `listen[]` array in `app/Providers/EventServiceProvider`.
-- Add your listeners (i.e. the ones from the providers) to the `SocialiteProviders\Manager\SocialiteWasCalled[]` that you just created.
-- The listener that you add for this provider is `'Anikeen\\Id\\Socialite\\AnikeenIdExtendSocialite@handle',`.
-- Note: You do not need to add anything for the built-in socialite providers unless you override them with your own providers.

 ## Configuration
 
-Copy configuration to config folder:

 You will need to add an entry to the services configuration file so that after config files are cached for usage in production environment (Laravel command `artisan config:cache`) all config is still available.

-## Implementing Auth
+### Event Listener
 
-This method should typically be called in the `boot` method of your `AuthServiceProvider` class:
+In Laravel 11, the default EventServiceProvider provider was removed. Instead, add the listener using the listen method on the Event facade, in your `AppServiceProvider` boot method:
+
+```php
+public function boot(): void
+{
+    Event::listen(function (\SocialiteProviders\Manager\SocialiteWasCalled $event) {
+        $event->extendSocialite('anikeen', \Anikeen\Id\Socialite\Provider::class);
+    });
+}
+```
+
+### Registering Middleware
+
+Append it to the global middleware stack in your application's `bootstrap/app.php` file:
+
+```php
+->withMiddleware(function (Middleware $middleware) {
+    $middleware->web(append: [
+        \Anikeen\Id\Http\Middleware\CreateFreshApiToken::class,
+    ]);
+})
+```
+
+### Implementing Billable
+
+To implement the `Billable` trait, you need to add the `Billable` trait to your user model.
+
+```php
+use Anikeen\Id\Billable;
+
+class User extends Authenticatable
+{
+    use Billable;
+
+    // Your model code...
+}
+```
+
+then, you can use the `Billable` trait methods in your user model.
+
+### App subscriptions (trusted apps, no user token)
+
+`subscriptions()` acts with the user's own access token and stops working when the user's login
+expired. Trusted apps can manage a user's subscriptions with the app's own token (client
+credentials, scope `subscriptions:client`) instead:
+
+```php
+$subscriptions = $team->owner->appSubscriptions(); // nothing is requested yet
+
+$subscription = $subscriptions->create([
+    'group' => $team->id,
+    'name' => 'Cloud Server S',
+    'unit' => 'hour',
+    'price' => 0.0137,
+    'idempotency_key' => "server:{$pendingServer->id}", // retries return the same subscription
+]);
+
+$subscription->checkout();             // bill the first period
+$subscription->pause();                // expires when the paid period ends
+$subscription->resume();               // expired subscriptions start a new period
+$subscription->revoke(refund: false);  // cancel
+
+$subscriptions->find($id);             // null if unknown or not this user's
+$subscriptions->all(['group' => $team->id, 'active' => true]);
+```
+
+The user's Anikeen ID is read from the billable's `anikeen_id` attribute
+(`AnikeenId::useUserIdField('…')` to change it). The app must be trusted by Anikeen ID; it sees the
+subscriptions it created (plus those of clients delegated to it).
+
+Failures throw `Anikeen\Id\Exceptions\ApiException` with `status` (0 = not reachable), a stable
+`error` code (`already_active`, `already_cancelled`, `not_active`, `already_paused`,
+`already_resumed`, `billing_address_missing`, `not_changeable`, `subscription_not_found`,
+`idempotency_key_conflict`) and `isNotFound()`, `isConflict()`, `isTemporary()`:
+
+```php
+try {
+    $subscription->revoke();
+} catch (ApiException $e) {
+    if ($e->isNotFound() || $e->error === 'already_cancelled') {
+        // already gone
+    } elseif ($e->isTemporary()) {
+        // retry later
+    } else {
+        throw $e;
+    }
+}
+```
+
+### App orders (trusted apps, no user token)
+
+Orders that bill the app's subscriptions, read with the app's token (scope `orders:client`):
+
+```php
+$team->owner->appOrders()->pending();         // unpaid orders of one user, oldest first
+app(AnikeenId::class)->appOrders()->pending(); // of all users
+$team->owner->appOrders()->find($orderId);     // null if unknown or not this user's
+```
+
+Each order has `status` (`processing` = current month, still collecting; `pending` = closed and not
+paid; `completed`; `cancelled`), the totals, `payment_attempts`, `next_payment_attempt_at` (null =
+no more automatic retries) and `last_payment_error`.
+
+### Change the default access token / refresh token field name
+
+If you access / refresh token fields differs from the default `anikeen_id_access_token` / `anikeen_id_refresh_token`, you can specify the field name in the `AppServiceProvider` boot method:
 
 ```php
 use Anikeen\Id\AnikeenId;
-use Anikeen\Id\Providers\AnikeenIdSsoUserProvider;
-use Illuminate\Http\Request;
 
-/**
+public function boot(): void
- * Register any authentication / authorization services.
- *
- * @return void
- */
-public function boot()
 {
-    Auth::provider('sso-users', function ($app, array $config) {
+    AnikeenId::useAccessTokenField('anikeen_id_access_token');
-        return new AnikeenIdSsoUserProvider(
+    AnikeenId::useRefreshTokenField('anikeen_id_refresh_token');
+}
+```
+
+### Implementing Auth
+
+This method should typically be called in the `boot` method of your `AppServiceProvider` class:

+Each order has `status` (`processing` = current month, still collecting; `pending` = closed and not
+paid; `completed`; `cancelled`), the totals, `payment_attempts`, `next_payment_attempt_at` (null =
+no more automatic retries) and `last_payment_error`.
+
+### Change the default access token / refresh token field name
+
+If you access / refresh token fields differs from the default `anikeen_id_access_token` / `anikeen_id_refresh_token`, you can specify the field name in the `AppServiceProvider` boot method:
 
 ```php
 use Anikeen\Id\AnikeenId;
-use Anikeen\Id\Providers\AnikeenIdSsoUserProvider;
-use Illuminate\Http\Request;
 
-/**
+public function boot(): void
- * Register any authentication / authorization services.
- *
- * @return void
- */
-public function boot()
 {
-    Auth::provider('sso-users', function ($app, array $config) {
+    AnikeenId::useAccessTokenField('anikeen_id_access_token');
-        return new AnikeenIdSsoUserProvider(
+    AnikeenId::useRefreshTokenField('anikeen_id_refresh_token');
+}
+```
+
+### Implementing Auth
+
+This method should typically be called in the `boot` method of your `AppServiceProvider` class:
+
+```php
+use Anikeen\Id\AnikeenId;
+use Anikeen\Id\Providers\AnikeenIdUserProvider;
+use Illuminate\Http\Request;
+use Illuminate\Support\Facades\Auth;
+
+public function boot(): void
+{
+    Auth::provider('anikeen', function ($app, array $config) {

             $app->make(AnikeenId::class),
             $app->make(Request::class),
             $config['model'],
             $config['fields'] ?? [],
