Integrate continuous PSF illumination over the physical slit and finite wavelength cells over detector pixels. Apply ADC displacement before slit clipping. Keep double-precision accumulation and restrict reuse to the evaluated physical inputs.

Part 09/29 of the Caltech review series. Review the diff against review/xs-08-spectral-integrals; the final destination is main.

Merge after series 08: scopesim.

Review focus: scopesim/optics/fov_utils.py; spectral_trace_list_utils.py; PSF and ADC effects.

Validation: 249 combined numerical/operating-point checks passed, with three inherited expected failures. Includes slit edges, off-slit light, photon integrals, ADC order, finite cells and mutable-input cache checks.

Lots of changes in optical train and FOV which may not align with upstream design.
