feat: port complete alias command logic from original implementation

Port all special logic from original alias commands:
- startCmdAlias: custom Args validation, startOnly logic, iface handling
- stopCmdAlias: iface flag handling and argument passing
- restartCmdAlias: simple delegation to restartCmd.RunE
- reloadCmdAlias: simple delegation to reloadCmd.RunE
- statusCmdAlias: simple delegation to statusCmd.RunE
- uninstallCmdAlias: iface flag handling and argument passing

All aliases now have exact same behavior as original implementation
including proper flag inheritance and argument handling.
