feat(web): implement telemetry dashboard with data visualization
Add a comprehensive telemetry dashboard page featuring real-time system statistics and metric visualization using recharts. - Integrate recharts for area and bar chart rendering - Implement TelemetryAPI client for stats, discovery, and chart data - Add dashboard UI with stat cards and responsive charts - Remove legacy nginx sub_filter proxy configuration in favor of direct API communication to telemetry.imrnes.team
