Renders large full-width navigation buttons with an icon, title, subtitle, optional badge counter, and a conditional visibility check.
BIGBUTTON — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
Expects the query to return columns: Title (col 0), Controller (col 1), Action (col 2), BadgeReport (col 3), Glyph (col 4), Colour (col 5), ShowReport (col 6). The title may contain a |-separated subtitle. If ShowReport evaluates to empty or "0", the button is suppressed. The badge counter is sourced from a sub-report name or a raw SELECT statement. Navigates to $siteurl$/Controller/Action on click.
