znetsixe 394a972d10 hydraulic efficiency η = (Q·ΔP)/P + asset registry rename ...

The pre-existing efficiency formula `η = flow/power` produced tiny SI-unit
values (m³/J ≈ 1e-5), was monotonic in ctrl for centrifugal-pump curves
(no interior peak), and made NCog collapse to 0 — which cascaded into MGC
reporting BEP-position 0.0% always. Replaced with hydraulic efficiency
η = (Q·ΔP)/P_shaft, the dimensionless 0..1 ratio that has a real BEP and
matches the form MGC's group-level math uses.

- prediction/efficiencyMath.js:
  * calcEfficiencyCurve takes pressureDiffPa; η = 0 when dP missing
  * calcCog guards (yMax > yMin) before computing NCog (was unguarded /0)
  * calcEfficiency falls back to predictFlow.currentF when measured ΔP is
    missing, so predicted-variant calls still produce a meaningful η before
    the differential measurement settles
- specificClass.js:
  * Asset-registry lookup renamed: 'machine' → 'rotatingmachine' (matches
    the datasets/assetData/ rename in generalFunctions). The error path
    quotes the new filename so operators can find it.
  * Two-call-site fix: with default-param stateConfig={}, the single-arg
    constructor path (BaseNodeAdapter calls `new Machine(this.config)`
    after pre-setting Machine._pendingExtras) was silently clobbering the
    pre-set extras. Only overwrite when the caller explicitly passes them.
  * Push port 0 deltas (notifyOutputChanged) after prediction updates so
    dashboards see state + predicted-flow changes as they happen.
- pressure/pressureRouter.js: routing + fallback hardening (the trigger
  for the bep-distance-cascade reproduction).
- display/workingCurves.js: Q-H curve generator extended.
- New tests:
  * test/integration/qh-curve.integration.test.js — Q-H curve shape
  * test/integration/bep-distance-cascade.integration.test.js — reproduces
    the dashboard report (absDistFromPeak=0, NCog=0, efficiency=0 after a
    setpoint move) at the unit level so future regressions fail loudly.

Full suite: 214/214 pass.
