Pull request overview

Adds new pytest coverage around GSolve’s report assembly/Excel export flow and the core least-squares solver functions, aiming to catch regressions in validation, branching, and terrain-correction consistency logic.

Changes:

• Add GSolveReport tests for table assembly, parameter sections, terrain-correction consistency checks, and to_excel() sheet-writing behavior.
• Add call_gsolve_lstsq / g_solver_lstsq tests for input validation, calibration-factor paths, loop handling branches, and percentile-clipping behavior.
