Fix same-day badge progress inflation on re-evaluation

[ccpk1]

Summary

• use canonical active-window totals for badge points and chore-count evaluation
• requeue gamification after post-statistics writes so badge checks see settled period buckets
• add engine and integration regressions to prove unrelated same-day events do not inflate badge progress

Validation

• ./utils/quick_lint.sh --fix
• python -m pytest tests/test_gamification_engine.py tests/test_badge_target_types.py -v --tb=line
• python -m pytest tests/test_badge_target_types.py tests/test_badge_periods_initialization.py tests/test_badge_helpers.py tests/test_badge_cumulative.py tests/test_gamification_engine.py tests/test_gamification_shadow_comparison.py tests/test_workflow_gamification_pending_queue.py -v --tb=line
