Add responsive adaptiveness for IoT Hub home, browse, and search pages

- Add MediaBreakpoints lt-xmd (≤1599), gt-xxl (≥2448) to constants
- Home: BreakpointObserver dynamically adjusts card counts per breakpoint
- Home: main-content container with 48px gap and responsive padding
- Home: hero icons positions/sizes adapt per breakpoint, hidden below ≤959px
- Home: subtitle line break after Solution Templates
- Home: installed button centered at ≤599px
- Browse: responsive card grid with compact type support (CF/RC/DEVICE)
- Search: responsive grid columns matching home page breakpoints
- Card component: min-width 0 for grid overflow prevention
- isCompactType includes DEVICE across all components
