Joseph Doherty 961e09430a feat(deploy): add site-a + site-b 2-node clusters to docker-dev
Extends the docker-dev compose with two additional, fully-isolated Akka
clusters representing distinct sites. Each site is a 2-node fused
admin+driver cluster (OTOPCUA_ROLES=admin,driver on both nodes), backed
by its own ConfigDb database so configuration state stays separate from
the main cluster and from the other site.

Cluster isolation: the three meshes share the same Akka system name
"otopcua" and remoting port 4053 (inside each container's own network
namespace), but their seed-node lists are disjoint — main seeds at
admin-a, site-a seeds at site-a-1, site-b seeds at site-b-1 — so gossip
doesn't cross between them.

Layout:
  Main cluster   ConfigDb=OtOpcUa        admin-a, admin-b, driver-a, driver-b
  Site A         ConfigDb=OtOpcUa_SiteA  site-a-1, site-a-2 (fused admin+driver)
  Site B         ConfigDb=OtOpcUa_SiteB  site-b-1, site-b-2 (fused admin+driver)

OPC UA endpoints exposed on host ports 4840-4845. Admin UIs reachable
through Traefik via Host-header routing:
  http://localhost               → main cluster (PathPrefix default)
  http://site-a.localhost        → site A
  http://site-b.localhost        → site B

`*.localhost` auto-resolves on macOS; Linux users add the two hosts to
/etc/hosts (or rely on the resolver's RFC 6761 behaviour).

# docker-dev companion to scripts/install/traefik-dynamic.yml. Routes three
# Akka clusters that share the Compose network:
#
# - Main cluster (default): PathPrefix(`/`) → admin-a / admin-b.
# - Site A cluster: Host(`site-a.localhost`) → site-a-1 / site-a-2.
# - Site B cluster: Host(`site-b.localhost`) → site-b-1 / site-b-2.
#
# Host-header rules are more specific than PathPrefix, so they win over the
# default router for the site hostnames automatically — no priority field needed.
