Re-configured load balancer for wss://staging-event.ainetwork.ai

• keep using HTTPS protocol (NOT changed to SSL protocol)
• backend port mapping: 443 -> 8080 => 443 -> 5100
• session affinity: disabled -> enabled (ip address based)

The reconfiguration was done for testnet and mainnet as well: wss://testnet-event.ainetwork.ai wss://mainnet-event.ainetwork.ai
