feat(demo): add Homepage dashboard configuration files

- services.yaml: all 13 user-facing services organized by category
  with Pi-hole and Grafana widgets for live stats
- widgets.yaml: greeting, datetime, search, and Pi-hole glances widget
- bookmarks.yaml: developer resource links (GitHub, Stack Overflow,
  Docker Hub, Grafana Docs, InfluxDB Docs)
- settings.yaml: layout configuration (row style, column counts),
  Docker provider via socket proxy, and branding

Previously only docker.yaml existed, resulting in a bare-bones
dashboard with no widgets, bookmarks, or layout.
