## 4. SuperAdmin Dashboard Widgets

### RevenueChart Widget
```php
// app/Filament/Widgets/RevenueChart.php
class RevenueChart extends LineChartWidget
{
    protected static ?string $heading = 'Monatliche Einnahmen';
    protected static ?int $sort = 1;

    protected function getData(): array
    {
        $data = PurchaseHistory::selectRaw('
            DATE_FORMAT(purchased_at, "%Y-%m") as month,
            SUM(price) as revenue
        ')
        ->groupBy('month')
        ->orderBy('month')
        ->limit(12)
        ->get();

        return [
            'datasets' => [
                [
                    'label' => 'Einnahmen (€)',
                    'data' => $data->pluck('revenue')->values(),
                    'borderColor' => '#3B82F6',
                    'backgroundColor' => 'rgba(59, 130, 246, 0.1)',
                ],
            ],
            'labels' => $data->pluck('month')->values(),
        ];
    }

    protected function getFilters(): ?array
    {
        return [
            '12_months' => 'Letzte 12 Monate',
            '6_months' => 'Letzte 6 Monate',
            '3_months' => 'Letzte 3 Monate',
        ];
    }
}
```

### TopTenantsWidget
```php
// app/Filament/Widgets/TopTenantsByRevenue.php
class TopTenantsByRevenue extends TableWidget
{
    protected static ?string $heading = 'Top Tenants nach Einnahmen';
    protected static ?int $sort = 2;

    protected function getTableQuery(): Builder
    {
        return Tenant::withCount('purchases')
            ->withSum('purchases', 'price')
            ->orderByDesc('purchases_sum_price')
            ->limit(10);
    }

    protected function getTableColumns(): array
    {
        return [
            Tables\Columns\TextColumn::make('name')
                ->label('Tenant')
                ->searchable()
                ->sortable(),
            Tables\Columns\TextColumn::make('purchases_sum_price')
                ->label('Gesamt (€)')
                ->money('EUR')
                ->sortable(),
            Tables\Columns\TextColumn::make('purchases_count')
                ->label('Käufe')
                ->badge()
                ->sortable(),
            Tables\Columns\TextColumn::make('event_credits_balance')
                ->label('Aktuelle Credits')
                ->badge(),
        ];
    }
}
```

### CreditAlertsWidget
```php
// app/Filament/Widgets/CreditAlerts.php
class CreditAlerts extends StatsOverviewWidget
{
    protected function getCards(): array
    {
        $lowBalanceTenants = Tenant::where('event_credits_balance', '<', 5)
            ->where('is_active', true)
            ->count();

        $totalRevenueThisMonth = PurchaseHistory::whereMonth('purchased_at', now()->month)
            ->sum('price');

        $activeSubscriptions = Tenant::whereNotNull('subscription_expires_at')
            ->where('subscription_expires_at', '>', now())
            ->count();

        return [
            StatsOverviewWidget\Stat::make('Tenants mit niedrigen Credits', $lowBalanceTenants)
                ->description('Benötigen möglicherweise Support')
                ->descriptionIcon('heroicon-m-exclamation-triangle')
                ->color('warning')
                ->url(route('filament.admin.resources.tenants.index')),
            StatsOverviewWidget\Stat::make('Einnahmen diesen Monat', $totalRevenueThisMonth)
                ->description('€')
                ->descriptionIcon('heroicon-m-currency-euro')
                ->color('success'),
            StatsOverviewWidget\Stat::make('Aktive Abos', $activeSubscriptions)
                ->description('Recurring Revenue')
                ->descriptionIcon('heroicon-m-arrow-trending-up')
                ->color('info'),
        ];
    }
}
```

## 5. Permissions und Middleware

### Policy für SuperAdmin
```php
// app/Policies/TenantPolicy.php
class TenantPolicy
{
    public function before(User $user): ?bool
    {
        if ($user->role === 'superadmin') {
            return true;
        }
        return null;
    }

    public function viewAny(User $user): bool
    {
        return $user->role === 'superadmin';
    }

    public function view(User $user, Tenant $tenant): bool
    {
        return $user->role === 'superadmin' || $user->tenant_id === $tenant->id;
    }

    public function create(User $user): bool
    {
        return $user->role === 'superadmin';
    }

    public function update(User $user, Tenant $tenant): bool
    {
        return $user->role === 'superadmin';
    }

    public function delete(User $user, Tenant $tenant): bool
    {
        return $user->role === 'superadmin';
    }

    public function addCredits(User $user, Tenant $tenant): bool
    {
        return $user->role === 'superadmin';
    }

    public function suspend(User $user, Tenant $tenant): bool
    {
        return $user->role === 'superadmin';
    }
}
```

### SuperAdmin Middleware
```php
// app/Http/Middleware/SuperAdminMiddleware.php
class SuperAdminMiddleware
{
    public function handle(Request $request, Closure $next)
    {
        if (!auth()->check() || auth()->user()->role !== 'superadmin') {
            abort(403, 'SuperAdmin-Zugriff erforderlich');
        }

        return $next($request);
    }
}
```

## Implementierungsreihenfolge
1. **Model & Migration:** PurchaseHistory, OAuthClient Tabellen
2. **TenantResource:** Erweiterung mit neuen Feldern, Relations, Actions
3. **PurchaseHistoryResource:** Vollständige CRUD mit Filtern und Export
4. **PAT-Tooling:** Management für Tenant-PATs (TBD)
5. **Widgets:** Dashboard-Übersicht mit Charts und Stats
6. **Policies & Middleware:** Security für SuperAdmin-Funktionen
7. **Tests:** Feature-Tests für Credit-Management, Permissions

Dieser Plan erweitert den SuperAdmin-Bereich um umfassende Billing- und Security-Management-Funktionen.
