Migrate tooling to homelab; add OTel observability stack
- Remove GlitchTip, Umami, Fider, Gotify, Uptime Kuma, Dozzle, Watchtower
  from prod docker-compose (now run on homelab)
- Add dozzle-agent on prod (127.0.0.1:7007) for homelab Dozzle to connect to
- Remove corresponding subdomain blocks from Caddyfile (now routed via
  Cloudflare Tunnel from homelab)
- Add homelab/docker-compose.yml: unified homelab stack with all migrated
  tooling services plus full OTel stack (Tempo 2.6.1, Loki, Prometheus,
  OTel Collector, Grafana)
- Add homelab/otel/: Tempo, Loki, Prometheus, OTel Collector configs +
  Grafana provisioning (datasources + dashboards)
- Add homelab/dozzle/users.yml for Dozzle auth
