Remove reported SPM data inputs

[MaxGhenis]

Summary

• stop exporting reported WIC, school meals, broadband, and SPM tax inputs from CPS outputs
• keep SNAP/SSI reported values only as build-time take-up anchors and drop them before saving
• rename data-backed housing and energy subsidy leaves to *_data, and calibrate SNAP loss against canonical snap

Dependency

Depends on PolicyEngine/policyengine-us#8263 for the new spm_unit_capped_housing_subsidy_data and spm_unit_energy_subsidy_data variables and removal of the old reported public variables.

GitHub unit-tests are expected to fail while CI installs released policyengine-us without those variables; local validation passes with #8263 installed editable. After #8263 is merged and released, this PR should bump the dependency/lock to that release and rerun CI.
