Function resolve_station_conditions_with_pressure_mode 

pub fn resolve_station_conditions_with_pressure_mode(
    temperature_c: f64,
    pressure_hpa: f64,
    altitude_m: f64,
    pressure_mode: PressureReferenceMode,
) -> (f64, f64)

Mode-aware counterpart of resolve_station_conditions (MBA-1397): identical for PressureReferenceMode::Absolute (byte-identical delegate — resolve_station_conditions itself now forwards here), and reduces an explicit QNH pressure to station pressure via resolve_station_pressure_with_mode for PressureReferenceMode::Qnh before applying the same standard-atmosphere fallback used when either input is left at its sea-level default.
