mKCP transport: Add cwndMultiplier

Replace legacy KCP buffer options with cwndMultiplier and maxSendingWindow across models and UI. Updated KcpStreamSettings in web/assets/js/model/inbound.js and web/assets/js/model/outbound.js (constructor, fromJson and toJson) to remove congestion/readBuffer/writeBuffer and use cwndMultiplier/maxSendingWindow instead. Updated web/html/form/outbound.html to reflect the new KCP fields in the stream form and to include extensive template formatting/markup cleanup for consistency and readability.
