Add 6 new utility services: gatus, mail-archiver, rustdesk, unifi, vaultwarden, watchyourlan

- gatus: status/uptime monitoring page with hot-reloaded config
- mail-archiver: IMAP email archive and full-text search (postgres backend)
- rustdesk: self-hosted remote desktop relay, cross-VLAN/FQDN docs
- unifi: UniFi Network Application with MongoDB init via Docker configs
- vaultwarden: Bitwarden-compatible password manager with SMTP prompts
- watchyourlan: network device tracker (host networking for ARP scanning)

All follow caddy_net container-routing pattern except rustdesk (raw TCP/UDP)
and watchyourlan (network_mode: host, incompatible with caddy_net).

README.md services table updated with all 6 new entries.
