chore(health): bump ZB.MOM.WW.Health* to 0.2.0

Picks up the additive per-entry `data` object in the canonical health JSON and
the cluster-view data the shared AkkaClusterHealthCheck now publishes (leader /
selfAddress / selfRoles / memberCount / unreachableCount).

No OtOpcUa code change is needed: the "akka" ready/active check is already the
shared ZB.MOM.WW.Health.Akka.AkkaClusterHealthCheck (Health/HealthEndpoints.cs),
so /health/ready starts carrying entries["akka"].data.leader on the bump alone.
Payloads from every other check are byte-identical — data is emitted only when a
check publishes some.

Prereq for the family overview dashboard (scadaproj
docs/plans/2026-07-22-overview-dashboard-impl-plan.md, Phase 2).

Verified: Host 21/21, AdminUI 692/692, Host builds 0 warnings.
Live rig check (admin node serves data.leader) deferred to the dashboard's
acceptance run.
