Add FindMyDevice, Frigate-Notify, and improve Caddy setup

New Docker applications:
- FindMyDevice (FMD) server for self-hosted Android device tracking
- Frigate-Notify for push notifications on Frigate AI detections

Caddy improvements:
- Interactive domain configuration during setup
- Comprehensive Caddyfile template with all services (commented)
- Clear instructions for caddy_net Docker network usage
- .env file with MY_DOMAIN variable

Frigate-Notify features:
- Auto-detects if Frigate and ntfy are installed
- Interactive setup for Frigate URL and ntfy topic
- WebAPI mode by default (polls Frigate every 30s)
- Config template with labels, zones, quiet hours
- Warns about public ntfy.sh privacy implications

+### Frigate + ntfy Notifications
+
+If you installed Frigate, ntfy, and Frigate-Notify, they work together:
+
+1. **Frigate** detects objects (person, car, etc.) on your cameras
+2. **Frigate-Notify** monitors Frigate for events
+3. **ntfy** sends push notifications to your phone
+
+**Subscribe to alerts:**
+```bash
+# On your phone: Install ntfy app, add topic "frigate-alerts"
+# Or visit: http://localhost:8090/frigate-alerts
+```
+
+**Customize alerts:** Edit `~/docker/frigate-notify/config.yml`
+- Change which objects trigger alerts (person, car, dog, package)
+- Set quiet hours for no notifications
+- Add multiple notification services (Discord, Pushover, etc.)
+
+### Caddy Reverse Proxy Network
+
+To route traffic through Caddy, containers must be on the `caddy_net` network:
+
+```yaml
+# Add to any container's docker-compose.yml:
+networks:
+  default:
+    name: caddy_net
+    external: true
+```
+
+Then uncomment the service in `~/docker/caddy/Caddyfile`.
