Use dashboard icons and vertical layout for Homepage

Layout:
- Change style from row to column for all groups
- Services within groups now list vertically
- Groups flow side by side naturally

Icons:
- Switch from si- prefixed icons to dashboard icons
- Dashboard icons are full color (grafana.png, prometheus.png, etc.)
