Setup Node v22 and build SoulSync WebUI

Install and use Node.js v22 during both install and update flows, and build the WebUI. Adds NODE_VERSION="22" setup_nodejs to install/soulsync-install.sh and ct/soulsync.sh, and runs npm ci and npm run build in /opt/soulsync/webui during install/update so the front-end assets are compiled. Existing Python venv and service restart logic remain unchanged.
