jschoubben 229c6a83d1 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.

// fail2ban's tools — reading and steering the live ban state. The jails themselves are declared
// resources (module.json); these three touch what the running daemon holds: what is banned now,
// and the manual ban/unban an operator reaches for. The daemon's state is fail2ban's own, so this
// is the only way to see or change it — the mesh reconciles the config, not the bans.
