Pull request overview

This PR updates tracer ordering conventions for galaxy_shearDensity_xi_t two-point statistics and adds warning suppression for loading old SACC format files. The key change standardizes the parameter order so that WeakLensing sources come first (source0) and NumberCounts sources come second (source1) in cross-correlation statistics.

• Standardizes tracer ordering for galaxy-shear density correlations across templates and tests
• Adds warning/output suppression when loading SACC files to handle old format files cleanly
• Updates test expectations to handle new warning messages from inverse covariance computations
• Refactors fixture naming to follow pytest conventions
