Renders a visually styled anchor button that links to # (no action), used as a placeholder or display-only button.
BTN_NOACT — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
Sub-reports from each query row are rendered before the button. The button's CSS class comes from self._Reportclass (defaults to btn-success btn-sm). The icon defaults to fa-eye unless self._Glyph is set. The href is always #, making this a non-navigating display element.
