Fix icons, add Anki, exclude dashboard self-reference

- Extend Tailwind source scan to lib/homelab_dashboard/ so icon classes
  in services_sync.ex are included in compiled CSS
- Add Anki service (hero-academic-cap) to icon and description maps
- Exclude 'devbox' (the dashboard itself) from the rendered service list
