[Application] show hazard exposure results

[SilverSupplier]

Summary

• Adds hazard exposure result summaries for fire and smoke in single-scenario result cards, graph tabs, and navigation panels.
• Adds batch comparison exposure tables and selected-scenario exposure details.
• Persists hazard exposure result artifacts and covers project save/load round-trip behavior.

Area

• Application
• Docs
• Build
• Analysis
• Chore

Architecture Check

• I kept the dependency direction application -> domain -> engine.
• I did not add Qt UI code to src/domain.
• I did not add domain or application dependencies to src/engine.
• I used src/ as the include root.

Verification

• cmake --preset windows-debug (not rerun; existing configured build tree reused)
• cmake --build --preset build-debug
• ctest --preset test-debug
• cmake --build --preset build-no-app-debug
• ctest --preset test-no-app-debug
• Not run (reason below)

Risks / Follow-up

• UI rendering was checked through the local app build path, but there is no automated Qt screenshot test for the new Exposure tabs yet.
• Pressure result persistence was split into PR [Application] persist pressure result artifacts #268 to keep this PR focused on hazard exposure display and persistence.
• Integration note: this PR overlaps with open PR [Domain] 운영 갈등 지표 및 결과 오버레이 구현 #267 in result navigation, workspace state, and result widget code paths. This PR intentionally does not resolve the cross-PR integration conflict. The PR that is merged later should rebase and reconcile src/application/ProjectWorkspaceState.h, src/application/ScenarioResultNavigation.cpp, and src/application/ScenarioResultWidget.cpp. Cross-PR UI integration should be handled by the later PR owner.
