Update PolicyEngine US to 1.633.2

[policyengine]

Summary

Update PolicyEngine US from 1.632.5 to 1.633.2.

This PR does not change the v1 API's policyengine_uk pin.

Why tests were failing

The failing test_utah check was not caused by policyengine-us 1.633.2 itself.

The legacy simulation gateway was reading shared Modal dicts that had been overwritten by policyengine-api-v2-alpha, so requests for us 1.633.2 were resolving to policyengine-v2-us1-633-2-uk2-75-1 instead of the old policyengine-simulation-* app family.

The old gateway calls run_simulation, and that app does not expose it. The live gateway error was:

Function 'run_simulation' not found on App 'policyengine-v2-us1-633-2-uk2-75-1'

The shared-registry root cause is being fixed in:

• Split api-v2 version registries from the legacy simulation registry policyengine-api-v2-alpha#215
• Split api-v2 version registries from the legacy simulation registry policyengine-api-v2-alpha#216

Legacy simulation API state

The legacy simulation API already owns the UK 2.78.0 pairing:

• policyengine-api-v2 main already pins policyengine-uk==2.78.0 in projects/policyengine-api-simulation/uv.lock
• live simulation-api-uk-versions[latest] = 2.78.0
• live simulation-api-uk-versions[2.78.0] = policyengine-simulation-us1-633-2-uk2-78-0

The live registries have now been split so:

• legacy simulation-api-* entries point to policyengine-simulation-*
• policyengine-api-v2-alpha uses api-v2-us-versions / api-v2-uk-versions

This PR remains a US-only update in the v1 API repo.

What changed (1.632.5 -> 1.633.2)

Added

• Move SC H4216 income tax reform from contributed reform to baseline, effective for tax years 2026 and later. This implements new tax rates (1.99%/5.21%), the SCIAD deduction with phaseout, and the 00 EITC cap.

Changed

• Updated programs.yaml to reflect current modeled program coverage and pending in-progress program implementations across TANF, CCDF, LIHEAP, SSI state supplements, and Colorado OmniSalud.

Fixed

• Fixed Maryland non-refundable EITC to cap at state income tax liability per section 10-704(c)(1), which previously overstated the credit by up to 50% of federal EITC for low-income households.
