Transform the dashboard into a single-pane-of-glass command center that blends operational metrics with business context from Gaiia subscriber data. - Extend insight schema with multi-source support (snmp, gaiia, system) - Add Oban workers for automated insight generation (device health, system, gaiia) - New Dashboard context with health score computation and site summaries - Rewrite dashboard LiveView with health overview, alert/insight feeds, site grid - Add source filter pills for insights with URL state management - Add metrics bar to site detail pages (device count, alerts, subscribers, MRR) - Add subscriber/MRR context to alert list site links - Add subscriber badges to device list site headers - Real-time PubSub updates for alerts on dashboard
