#1360 made Auto-crop all frames and Auto Skew apply the Flat Field the way the render does. That left four copies of the same block, in run_pipeline, Roll Analysis and the two detection paths: skip a stitch or an embedded-lens frame, cut the gain to the half frame, and turn it by the frame's tag (#1359). The detection paths had already drifted from the render once, which is what #1360 fixed.

flatfield_source() in services/rendering/lens.py now holds that block, and all four call sites use it. Behaviour is unchanged. A new test covers the helper's skip, cut and turn, and make all passes.

run_pipeline, Normalization, Auto-crop all frames and Auto Skew each
repeated the stitch / embedded-lens gate, the half-frame gain cut and
the orientation turn. flatfield_source() in services/rendering/lens.py
holds that logic once, so the four paths cannot drift. No behavior
change; run_pipeline keeps its skip_flatfield flag at the call site.
