Fix: TeleBot order deletion and bot activity tracking

**Fixes Applied:**

1. **Order Deletion Authorization (HTTP 401)**
   - Added [AllowAnonymous] to CancelOrder endpoint
   - Allows customers to cancel orders using IdentityReference
   - File: LittleShop/Controllers/OrdersController.cs:160

2. **Bot Activity Tracking Hostname**
   - Changed littleshop-admin:8080 → littleshop:5000
   - Fixed DNS resolution errors in production
   - Files: TeleBot/appsettings.json, BotActivityTracker.cs, docker-compose.hostinger.yml

3. **Tor Proxy Investigation**
   - Analyzed SOCKS connection failures
   - Tor is working correctly, API blocks exit nodes (expected)
   - Fallback to default currencies working as designed
