[Domain] Add door closure crowd response

[SilverSupplier]

Summary

• Centralizes connection block active schedule semantics in domain helpers and reuses them from control/runtime display paths.
• Adds door-closure detection, patience/ready state, pre-ready slowdown, ready-time rerouting, and deterministic in-zone hold targets when no alternate exit is available.
• Allows finite closure expiry to clear no-exit state and retry route planning.

• Analysis

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

• git diff --check
• MSBuild safecrowd_tests.vcxproj Debug x64
• build/vs2022/windows-debug-no-app/Debug/safecrowd_tests.exe
• MSBuild safecrowd_app.vcxproj Debug x64
• cmake/ctest presets not run; existing generated VS projects were used because cmake is not available on PATH in this workspace.

Risks / Follow-up

• The motion update now checks blocked planned connections before zero-delta waypoint-progress advancement so a closed door cannot be skipped by proximity tolerance.
• Hold targets are deterministic and remain inside the current zone; they are not a full crowd queueing model.
