Renders a small anchor button that links to an arbitrary URL, with optional sub-report pre-rendering and FontAwesome icon.
BTN_HREF2 — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
Param1 encodes the full target URL and up to three additional parameters separated by ^. The button's CSS class comes from self._Reportclass (defaults to btn-primary btn-sm). The icon defaults to fa-eye unless self._Glyph is set. Unlike ObjReportBtn_href, the URL is used as-is rather than being prefixed with /report/rep=.
