🚀 New Features

Multi-Service Load Balancing
1. Multiple Endpoints Support: Configure multiple DeepLX API endpoints with load balancing
2. Load Balancing Strategies: Random, Round-Robin, and Weighted distribution algorithms
3. Automatic Failover: Smart switching between endpoints when one fails
4. Service Health Monitoring: Real-time status tracking with visual indicators

Enhanced Testing System
1. Auto-Test on Add: New endpoints automatically tested before saving
2. Manual Testing: "Test" button for each configured endpoint
3. Edit-Time Validation: Endpoints tested when being updated
4. Smart Duplicate Prevention: Blocks duplicate URL+Token combinations

Improved User Interface
1. Status Badges: Visual error indicators with HTTP status codes
2. Change Detection: Update button only enabled when changes are made
