feat(qualification): add typed business decision authoring

[abrichr]

Summary

• Add a qualification form for reviewed human decisions.
• Capture authorized roles, two to four finite options, exact successors, optional evidence, expiry, and one live revalidation check.
• Support existing workflow graphs and canonically lifted linear recordings.
• Save through Flow's exact business-decision schema. No raw workflow JSON is required.
• Keep all other qualification controls available when the embedded Flow version lacks this capability.

Runtime semantics

One signed answer selects one qualified branch for one run. The next action still runs its normal authorization, identity, postcondition, and effect checks. An answer does not prove success and does not change future policy.

Dependency

Depends on OpenAdaptAI/openadapt-flow#343. Desktop currently pins Flow 1.27.1. Merge can be safe because the control is capability-gated, but the control stays unavailable until Desktop pins the first published Flow release that contains PR 343.

Validation

• Focused frontend tests: 3 passed.
• TypeScript and Vite production build passed.
• Desktop qualification suite against the exact Flow branch: 31 passed.
• Ruff passed for changed Python files.

The final repeat stopped after the source checks and frontend build because the shared disk became full. The same 31-test cross-repository suite had passed before that repeat. I removed only the generated virtual environments, node modules, build output, and UV cache that this task created.
