The TUI provides a dashboard with tabs for:
  - Dashboard:   Network overview and health
  - Nodes:       Node status and management
  - Chains:      Chain status and block heights
  - Validators:  Validator set and uptime
  - Logs:        Live log streaming

NAVIGATION:

  Tab/Arrow   Navigate between tabs
  1-5         Jump to tab by number
  r           Refresh data
  q           Quit

Examples:
  lux tui
  lux tui --endpoint http://localhost:9640`,
		RunE: func(_ *cobra.Command, _ []string) error {
			model := app.NewApp()
			if endpoint != "" {
				model.SetEndpoint(endpoint)
