fix(pipelines): clear today's real cron errors + kill monitoring false alarms

Real errors fixed (all verified by manual run):
- price_monitor.py: shares None -> TypeError at L584 (now completes 3m7s,
  full 39-stock reassess + zone triggers + Dad push)
- market_insight.py: net_inflow None -> TypeError at L142 (now 0.3s, 5 insights)
- promote_candidates.py: add busy_timeout=30s (DB lock under concurrent writes)
- premarket_full_review.py: 12-dim analysis now detached background launch
  (was doomed by cron 120s script timeout no matter what)

Systemic:
- HERMES_CRON_SCRIPT_TIMEOUT=600 drop-in for both gateway services
  (fixes mofin_health SIGTERM, market_watch timeout, memory_guardian timeout)
- sync_profile_scripts.sh: re-hardlink deploy->profile scripts after every
  deploy (scp replaces files = new inode = broken hardlink = cron silently
  runs stale code; this caused promote to keep failing after my first fix)

Monitoring false-alarm fixes (the '花瓶' problem):
- mofin_health.py: legacy JSONs that migrated to DB (multi_tf_cache/
  macro_context/market/live_prices/price_history/macro_risk_state) no longer
  warn 'no readers'; marked as migrated
- NEW db_freshness section: real pipeline health from DB tables
  (mtf_cache 0.4h / macro_context_log 2h / market_snapshots 2h /
  live_prices 0.4h / price_events.json 0.4h — ALL HEALTHY)
- price_events freshness reads live JSON store (DB table is legacy)
- market.json placeholder created (13+ scripts have fallback paths)

Investigation notes: wiki-self-growth 03:04 key1 429 predates full key6
activation on default gateway; current 8642 verified on key6 and working.
Weekend 'Blocked' jobs verified fixed (vacuum_state_db passes).

+
+背景：老爸发现盘前全量重评只更新了技术参数，12维LLM深度分析(full_analysis)为空/陈旧。
+
+已落地的系统改动(已全部部署到246并提交git)：
+1. premarket_full_review.py 新增 Step 1.5：每交易日08:10自动跑 batch_reassess.py --type holding --today，14只持仓12维分析每日强制刷新
+2. batch_reassess.py 升级：--type holding|watchlist|all 全覆盖；分析超20h视为过期自动重评；现金/总资产改为从 portfolio_summary 实时读取(不再硬编码)；港股前缀修复(00700等5位代码)
+3. 新增每日12:30 cron「自选12维分析补全-每日午间」(watchlist_12d_backfill.py)，109只缺分析的自选股每日补全
+4. 验证：300308 已生成1920字12维分析(信号=观望)并写入DB；当前正在后台跑14只持仓的全量补评(/tmp/holdings_12d_backfill.log)
+
+需要知微做的：
+- 验证今天开盘简报/盯盘里能正常引用最新12维分析
+- 观察今日12:30自选补全任务是否正常触发
+- 有问题在kanban回复或XMPP找笑笑"""
