connection: логировать только connect/reconnect/disconnect; фиксы конфига чатгуи 

- категория connection теперь только жизненный цикл соединения; INIT/PING/keepalive
  переклассифицированы в ETCP/SOCKET/KEEPALIVE/REALITY/ROUTING, удалены дубли
- settingsdialog: устранён дубль my_node_name в конфиге (двухпроходная запись + только при изменении)
- storagesettingspage: канонические ключи storage_total_size/storage_unit_size с суффиксом M/G
- audiodevicesettingspage: compressor_max_gain_db min 0→1
- etcp_connections: %s-баг в логе TCP link (addr → sockaddr_storage_to_str)
- docs/sample: [chatserver], актуализированы ключи хранилища
