[Application] add run-screen execution controls

[SilverSupplier]

Summary

• Add a "Run settings" group to the simulation run screen (ScenarioRunWidget) with Time limit, Sample interval, Repeats, and Seed controls plus an "Apply selected & restart" action, so run parameters can be set from the run screen as described in the project report (section 5.3).
• Apply writes the values into the selected scenario's execution config (not the whole batch), resets the batch runner, rebuilds the run canvas/cards, and re-selects the edited scenario's run. The change is also synced back to the return-to-authoring state.
• Apply asks for confirmation before discarding completed/cached simulation results, so a finished run is not lost by accident.
• Controls initialize from the selected scenario's execution config and update when the selected run changes.

Area

• Engine
• Domain
• Application

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
• cmake --build --preset build-debug
• ctest --preset test-debug
• Not run (reason below)

Built the Qt app in release: cmake --build --preset build-release --target safecrowd_app -> succeeds. UI-only change driven through the existing domain execution config and batch runner reset.

Risks / Follow-up

• Settings apply per selected scenario; "Apply selected & restart" restarts the batch and clears cached results after confirmation when a completed run would be discarded.
