docs(historian): fix-wave docs and stale comments

Browse Source 
- Historian.md: Empty samples always Bad (writer/updater/read clamp),
  long-name refusal, 5 s bootstrap failure cache, AtTime after now, info-bit
  masking, HistoryUpdate does NOT type-check (M-1 decision), DeleteRaw
  needs both bounds, reverse Raw paging, the historian/historization metric
  prefixes, and provisioning numeric-only lines qualified as Gateway.
- CLAUDE.md numeric-only lines qualified as Gateway backend.
- Stale 'sole historian' lines in DriverLifecycle, ServiceHosting and the
  retired Wonderware stub; Client.CLI exit-code contract.
- ServerHistorianOptions: Endpoint/Backend XML docs untangled, Validate()
  indented; Program.cs comments are backend-neutral; T10 week-test day count.

| Process | Project | Runtime | Platform | Responsibility |
|---|---|---|---|---|
| **OtOpcUa Host** | `src/Server/ZB.MOM.WW.OtOpcUa.Host` | .NET 10 | AnyCPU | Single fused binary. The resolved [`EffectiveRoles`](#role-gating) decides what to mount: `admin` (Blazor + auth + control-plane singletons), `driver` (OPC UA endpoint + per-driver actors), or both. |
| **ZB.MOM.WW.HistorianGateway** *(external — separate deployment)* | not in this repo | .NET 10 | — | The sole historian backend. OtOpcUa talks gRPC to it (via the `ZB.MOM.WW.HistorianGateway.Client` package) for HistoryRead, alarm `SendEvent`, and continuous `WriteLiveValues`. Must run `RuntimeDb:Enabled=true` + `RuntimeDb:EventReadsEnabled=true`; the API key must carry `historian:read` + `historian:write` + `historian:tags:write`. |
| **ZB.MOM.WW.HistorianGateway** *(external — separate deployment)* | not in this repo | .NET 10 | — | The default historian backend (`ServerHistorian:Backend=Gateway`; `SqlServer` needs no sidecar). OtOpcUa talks gRPC to it (via the `ZB.MOM.WW.HistorianGateway.Client` package) for HistoryRead, alarm `SendEvent`, and continuous `WriteLiveValues`.

Galaxy access still uses the separately-installed **mxaccessgw** sidecar (see `docs/v2/Galaxy.ParityRig.md`); the gateway owns the MXAccess COM bitness constraint (its worker is x86 net48). Nothing in the OtOpcUa repo carries that constraint anymore. (The bespoke Wonderware historian sidecar this deployment used to ship was retired — see [drivers/Historian.Wonderware.md](drivers/Historian.Wonderware.md).)
