The azimuthal-integration solid-angle correction used cos^3(2*theta), where 2*theta is the true scattering angle (from LabCoord, including detector tilt). The solid angle of a flat pixel actually depends on the incidence angle to the detector normal, cos(alpha) = det_distance / |detector-frame position|, which is invariant under detector tilt (rot1/rot2/rot3). Only for an untilted detector do the two agree. Switch CalcAzIntSolidAngleCorr(x,y) to the tilt-invariant form, matching PyFAI solidAngleArray and MAX IV azint. Drop the q-only overload (it can only ever be the untilted approximation and was used only in tests) and move its test onto the (x,y) form; add a tilt-invariance test. XtalOptimizer's residual reconstructed each spot's lab position from rot1/rot2 only, hardcoding rot3 = 0, while the rest of the pipeline (and its own spot selection) used the full PONI rotation. An imported non-zero rot3 was therefore silently dropped during refinement. Bake rot3 into the residual as a fixed Rz(-rot3) so refinement stays consistent (no-op when rot3 == 0). Polarization and azimuthal binning already honoured rot3 via the full PONI rotation (Phi_rad), validated against PyFAI chi() by the existing rot3 phi tests.
