feat(networking): migrate host services from ZeroTier to Tailscale

- replace legacy IP addresses with Tailscale MagicDNS names
- route Prometheus scraping and exporter firewall access through Tailscale
- wait for Tailscale before starting Prometheus
- restrict service UI ports to the Tailscale interface
- update PostgreSQL and Transmission access rules
- remove Jeeves ZeroTier configuration and Docker host overrides
