refactor: pass rootCmd as parameter to Init*Cmd functions

- Update all Init*Cmd function signatures to accept rootCmd parameter:
  * InitServiceCmd(rootCmd *cobra.Command)
  * InitClientsCmd(rootCmd *cobra.Command)
  * InitLogCmd(rootCmd *cobra.Command)
  * InitUpgradeCmd(rootCmd *cobra.Command)
  * InitRunCmd(rootCmd *cobra.Command)
  * InitInterfacesCmd(rootCmd *cobra.Command)

- Update function calls in cli.go to pass rootCmd parameter
- Update InitInterfacesCmd call in commands_service.go

Benefits:
- Eliminates global state dependency on rootCmd variable
- Makes dependencies explicit in function signatures
- Improves testability by allowing different root commands
- Better encapsulation and modularity
