Surfaces network_status.json in the WebUI, attention-only: a rose badge
+ dashboard banner appear ONLY when conflicts_found, with a details panel
listing the stranded apps and a 'Heal now' button that runs the heal
through the task pipeline (libreportal system network heal). Re-reads on
task completion via taskRefresh.
Cloned from update-notifier; the badge anchors just after the update
badge so the two coexist in a stable order. New --page-network hue.
Wired into system-loader scripts[], topbar onTopbarReady, and index.html.
