Simplify and optimize Jeedom logo SVGs

Streamline six logo SVGs by replacing the complex grouped logomark and embedded Adobe Illustrator PGF data with simplified path/rect elements and cleaned metadata. Files updated: core/img/logo-jeedom-petit-nom-blanc.svg, core/img/logo-jeedom-petit-nom-couleur.svg, core/img/logo-jeedom-petit-nom-noir.svg, core/img/logo-jeedom-sans-nom-blanc.svg, core/img/logo-jeedom-sans-nom-couleur.svg, core/img/logo-jeedom-sans-nom-noir.svg. This reduces SVG complexity and size, improves rendering and styling consistency while preserving the visual appearance.
