feat(qualification): capture local institutional judgment cases

[abrichr]

Summary

Adds the optional Desktop qualification path for reviewed institutional-judgment cases.

• Captures reviewed typed facts, source provenance, a local evidence inventory, optional local review note, contrast cases, and the three disposition states.
• Creates a reciprocal automatic-rule pair atomically when the reviewer records a contrast case.
• Uses only Flow-owned local contracts and the qualification.set_judgment_cases capability.
• Preserves direct decision authoring as the fast path.
• Does not create a runtime decision, a signer, a policy inference path, or a VERIFIED outcome.

Dependency

This draft depends on Flow PR #344. The embedded Flow pin stays unchanged until a reviewed Flow release exists.

Validation

• Focused UI tests: JudgmentCaseCapture, BusinessDecisionAuthoring, Qualification
• Production UI build
• Python compile: engine/qualification.py and engine/dispatch.py
