feat(lotto-agent): sync_evolver_activity 매일 09:30 cron + 멱등 가드 + 3 테스트

- LottoAgent.sync_evolver_activity(): lotto-lab evolver status polling → agent_office.db task+log 미러링
- UTC 날짜 기준 멱등 guard (get_tasks_by_agent_date_kind 활용)
- 일요일(dow=6) → 5 clamp (lotto-lab trials는 0~5)
- 월요일 6-trial 완성 시 evolver_generate task 추가 생성
- scheduler.py: lotto_evolver_activity_sync cron 09:30 등록
- tests: creates_apply_task / idempotent / no_picks_no_task 3종
