Fix #2203 : Improve Spanwise Section Error Handling in Turbomachinery Simulations

[aryan0931]

Proposed Changes

This PR aims to:

• Modify ComputeNSpan in CPhysicalGeometry.cpp to throw a detailed error if fewer than 2 spanwise sections are detected, prompting users to verify hub-to-shroud edge definitions in their mesh.
• Improve the error message for unequal inflow and outflow spanwise sections, clarifying it’s likely a mesh issue and recommending mesh regeneration.
