refactor(curves): canonical axis Nm³/(h·m² membrane) for all diffuser suppliers
Previously each curve file stored x in whatever convention the vendor used (per-element Nm³/h for Jäger/GVA, per-element Sm³/h for PIK/PRK, per-m² for Aerostrip). That meant the diffuser physics couldn't read the data uniformly — selecting Aerostrip vs Jäger would feed wildly different axes to the same interpolator. All five curves now use the same canonical X: specific air flux in Nm³/(h·m² membrane). Y stays SSOTR in g O₂/(Nm³·m); coverage % is the parametric key. Per-file conversions: - jaeger-jetflex-td-65-2-g-epdm-1000: x divided by 0.18 m² perforated area (stated on the data sheet). - gva-elastox-r: x divided by 0.18 m² placeholder mirroring Jäger TD-65 (no real GVA sheet exists — see _meta note). - aerostrip-phoenix: native already in Nm³/(h·m²) — no x change. _meta area normalised to 1.0 m² per "element" so users set `elements` = total installed membrane area in m². - pik300, prk300 (Sulzer ABS 300 mm disc): native was Sm³/h/disc on X and g O₂/(Sm³·m) on Y. Converted to canonical Nm³ basis (DIN-1343) by X × 0.9319 / 0.07, Y × 1.0732. Each disc = 0.07 m² membrane. Supplier naming fixed: pikprk → sulzer, aquaconsult → aquaconsult-entec. PIK = perforated EPDM, PRK = perforated PUR. Config schema: new diffuser.membraneAreaPerElement field (nullable, default null) so a node can override the curve's stored area. When null, specificClass reads _meta.membraneArea_m2_per_element from the resolved curve. 246/246 generalFunctions tests still pass.
