fix(audit): candidates UPSERT保计算列+market_scanner INSERT对齐表结构+拆除sync_decisions_to_db地雷

举一反三审计结果:
- accumulation_scanner: INSERT OR REPLACE整行替换,promoted=1的候选被重置score/promoted/log
  → ON CONFLICT DO UPDATE只更新扫描器自有列(cron活跃,今日必修)
- market_scanner: INSERT引用表中不存在的列(price/score/entry_low等),实测必失败
  → 对齐真实schema+同款UPSERT(孤儿脚本顺手修)
- sync_decisions_to_db.py: 全表DELETE再从已不存在的decisions.json重建,地雷→归档
