- Fix Trojan protocol to use 'server_name' instead of 'tls_settings.server_name'
- Fix Hysteria protocol to use 'tls.server_name' instead of 'tls_settings.server_name'
- Align with Server model configuration and General protocol implementation
- Resolves missing SNI domains in sing-box configuration generation
This fixes the inconsistency where SNI domains were missing for certain
protocols while working correctly in General protocol handler.
