Renders a Bootstrap grid of large icon buttons that navigate to internal pages or open modal forms, one button per query row.
MENU — set as ReportType in def_report.
def Render(self, Param1="", Param2="", Param3="") -> str:
Each query row supplies: block/title text (col 0), subblock/subtitle text (col 1), rank (col 2), target (col 3), FontAwesome glyph (col 4), extra CSS class (col 5), parameters (col 6). Special target values: #modalform loads a form into a modal; #search opens a search modal. All other targets are used directly as href values. Modal loading shows a spinner on the icon while content loads.
