Aperture definition for SDDP backward-pass scenario sampling.

An Aperture represents one hydrological (or stochastic) realisation used in the SDDP backward pass. Each aperture references a source scenario whose affluent data (flow bounds) are applied to the cloned phase LP before solving. The source scenario can come from:

1. The regular forward-scenario definitions (in the standard input directory).
2. An aperture-specific scenario stored in a dedicated aperture_directory (see SddpOptions::sddp_aperture_directory).

When no explicit aperture_array is provided in the Simulation, the SDDP solver falls back to the legacy behaviour controlled by sddp_num_apertures (first N scenarios or all scenarios).
