@* Report tail — spacer row + italic footer line ("Stand: dd.MM.yyyy"). Note: the existing code used colspan="4" here even in reports whose table only has 3 columns; preserved as-is so the visual is unchanged. Callers can override via the Colspan parameter. *@   @Footer @code { [Parameter, EditorRequired] public string Footer { get; set; } = ""; [Parameter] public int Colspan { get; set; } = 4; }
