Convert four more hal modules: bookshelf, unifi, fail2ban, marrytts

- bookshelf: Servarr v1 fork on the radarr template (4 tools).
- unifi: portainer-shaped tooled app (7 tools, 9 ports), settings-merged config.
- fail2ban: host-level security module mirroring firewall (service + restart-on,
  no container); ban actions preserved as source ufw/iptables and FLAGGED to be
  rewritten nftables-native before it actually bans.
- marrytts: manifest-only plain container (no tools), like resolv-conf.

All typecheck against the built @novox/mesh-sdk; service images digest-pinned.
Held from merge pending the hq initialization reconciliation.
