Refactor: Align system with gateway_users architecture

- Fixed database relationships: LlmRequest now properly uses gateway_user_id instead of user_id
- Updated Models: GatewayUser and LlmRequest relationships corrected
- Removed User->llmRequests relationship (admin users don't have LLM requests)
- Simplified Dashboard: Now shows Gateway User statistics instead of admin users
- Removed obsolete Budgets management pages (budgets handled directly in gateway_users)
- Removed User Budgets admin section (redundant with gateway_users management)
- Fixed view errors: Added null-checks for user_id in keys views
- Updated navigation: Removed Budget and User Budget links
- Updated routes: Cleaned up unused BudgetController and UserManagementController routes
- Simplified StatisticsService: Focus on gateway_users and basic metrics only

-## 📝 Nächste Schritte
+## 🔐 Sicherheit
 
-### 1. Models erstellen
+### Production Checklist
 
-Folge dem Implementierungskonzept in `LARAVEL_IMPLEMENTATION.md`:
+Vor dem Production-Einsatz:
 
-```bash
+1. ✅ `.env` Konfiguration:
-docker compose exec laravel php artisan make:model GatewayUser
+   ```env
-docker compose exec laravel php artisan make:model ApiKey
+   APP_ENV=production
-docker compose exec laravel php artisan make:model UsageLog
+   APP_DEBUG=false
-docker compose exec laravel php artisan make:model Budget
+   APP_KEY=... (sicher generieren!)
-docker compose exec laravel php artisan make:model ModelPricing
+   ```
-```
 
-### 2. Controllers implementieren
+2. ✅ Admin-Passwort ändern
 
-```bash
+3. ✅ MariaDB Root-Passwort ändern
-docker compose exec laravel php artisan make:controller DashboardController
-docker compose exec laravel php artisan make:controller GatewayUserController --resource
-```
 
-### 3. Views erstellen
+4. ✅ phpMyAdmin deaktivieren oder absichern
 
-Die Views werden in `laravel-app/resources/views/` erstellt.
+5. ✅ SSL/TLS einrichten
 
-Struktur:
+6. ✅ Laravel Caches aktivieren:
-```
+   ```bash
-resources/views/
+   php artisan config:cache

+
+Multi-provider LLM Gateway supporting OpenAI, Anthropic, Google Gemini, DeepSeek, and Mistral AI.
+
+## Authentication
+
+All API requests require authentication via API key in the `Authorization` header:
+
+```
+Authorization: Bearer llmg_your_api_key_here
+```
+
+Gateway users receive API keys from the admin interface. Each key is linked to a specific gateway user 
+with their own budget limits, rate limits, and provider credentials.
+
+## Providers
+
+- **openai** - OpenAI models (GPT-4, GPT-3.5-turbo, etc.)
+- **anthropic** - Anthropic Claude models (Claude 4, Claude 3.5 Sonnet, etc.)
+- **google** - Google Gemini models (Gemini Pro, Gemini Flash, etc.)
+- **deepseek** - DeepSeek models (DeepSeek Chat, DeepSeek Coder)
+- **mistral** - Mistral AI models (Mistral Large, Mistral Medium, etc.)
+
+## Rate Limits
+
+Each gateway user has configurable rate limits (default: 60 requests/hour).
+Rate limit information is returned in error responses when exceeded.
+
+## Budgets
+
+Monthly budget limits are enforced per gateway user. Costs are calculated based on 
+token usage and provider-specific pricing.
+
+## Error Handling
+
+The API returns structured error responses:
+
+- **400**: Bad Request - Invalid parameters
+- **401**: Unauthorized - Invalid or missing API key
+- **402**: Payment Required - Budget exceeded
+- **403**: Forbidden - User blocked
+- **429**: Too Many Requests - Rate limit exceeded
+- **500**: Internal Server Error - Unexpected error

+# Laravel LLM Gateway API
+
+Multi-provider LLM Gateway supporting OpenAI, Anthropic, Google Gemini, DeepSeek, and Mistral AI.
+
+## Authentication
+
+All API requests require authentication via API key in the **Authorization** header:
+
+```
+Authorization: Bearer {your_api_key_here}
+```
+
+Gateway users receive API keys from the admin interface. Each key is linked to a specific gateway user with their budget limits, rate limits, and provider credentials.
+
+## Providers
+
+The gateway supports the following LLM providers:
+
+* **openai** - OpenAI models (GPT-4, GPT-3.5-turbo, etc.)
+* **anthropic** - Anthropic Claude models (Claude 3, Claude Sonnet, etc.)
+* **gemini** - Google Gemini models (Gemini Pro, etc.)
+* **deepseek** - DeepSeek models (DeepSeek Chat, DeepSeek Coder)
+* **mistral** - Mistral AI models (Mistral Large, Mistral Medium, etc.)
+
+## Rate Limits
+
+Each gateway user has configurable rate limits (default: 60 requests/hour). Rate limit information is returned in error responses when exceeded:
+
+```json
+{
+  "error": "Rate limit exceeded",
+  "limit": 60,
+  "reset_at": "2024-01-15T14:30:00Z"
+}
+```
+
+## Budgets
+
+Monthly budget limits are enforced per gateway user. Costs are calculated based on token usage and provider-specific pricing. When the budget is exceeded, requests return:
+
+```json
+{
+  "error": "Budget exceeded",
+  "current": 150.50,
+  "limit": 100.00
+}
+```
+
+## Error Handling
+
+The API returns structured error responses:
+
+* **400** Bad Request - Invalid parameters
+* **401** Unauthorized - Invalid or missing API key
+* **403** Forbidden - Budget exceeded
+* **404** Not Found - User blocked
+* **429** Too Many Requests - Rate limit exceeded
+* **500** Internal Server Error - Unexpected error
+
+## Cost Tracking
+
+All requests are logged with:
+* Model used
+* Input/output tokens
+* Calculated cost
+* Provider response time
+* Error details (if any)
+
+Administrators can view detailed usage analytics in the admin interface.
