fix: param-key mapping, phantom ops, and delete/update maps — close #12-#15

- #12: Remove tag from DELETE_PARAM_KEY (DeleteTag uses {id}, not {tag})
- #13: Remove 5 phantom execute ops (RunServerRefreshContainers/RunCommand/Scripts/Copy/Move)
- #14: Remove user_group from UPDATE_REQUEST_MAP (UpdateUserGroup doesn't exist)
- #15: Server-scoped execute ops pass {server} not {id}; RunSync passes {sync} not {id}
