docs(health): resolve spec/contract/gaps consistency (review fixes)
Applies canonical resolutions for eight settled decisions:
- GAPS: remove three stale "Decisions still open" bullets (#1 IActiveNodeGate placement, #2 GrpcChannel type, #3 OtOpcUaCompat named constant)
- Shared contract: AkkaClusterHealthCheck, ActiveNodeHealthCheck constructors take IServiceProvider (lazy ActorSystem, Degraded-when-not-ready)
- Shared contract: AkkaActiveNodeGate takes IServiceProvider; reads SelfMember+leader directly, null-guarded; does not proxy ActiveNodeHealthCheck
- Shared contract: DatabaseHealthCheckOptions.Probe renamed to ProbeQuery; consumer matrix updated
- Shared contract: settled AddZbHealthChecks open question removed (spec §5 is per-project AddHealthChecks)
- SPEC §2.2: OtOpcUaCompat Leaving/Exiting cell updated from — to Degraded + footnote; §2.3 startup-safety note added
- README: status line corrected from "built and tested" to "scaffolded … implementation is follow-on (task #7)"; IActiveNodeGate "left per-project" bullet removed
- OtOpcUa current-state: AddZbHealthChecks → AddHealthChecks().AddCheck<...>(); IClusterRoleInfo note reframed as accepted trade-off
- ScadaBridge current-state: IActiveNodeGate bullet rewritten — interface moves to ZB.MOM.WW.Health on adoption, InboundApiEndpointFilter references shared interface
