feat(signals): 新增价格上穿/下穿 MA5 MA10 信号

- pipeline.py: compute_signals() 与 compute_enriched_today() 双路径
  新增 signal_ma5_breakout/breakdown、signal_ma10_breakout/breakdown
  (盘中路径同步补 _prev_ma10 到 sig_prev)
- ENRICHED_COLUMNS 登记新列
- signals.ts: BUILTIN_SIGNAL_DEFINITIONS 加 4 条定义
- monitor.py: _SIGNAL_CN 加 4 条中文标签

注: 价格上穿/下穿 MA20 已有 (signal_ma20_breakout/breakdown), 本次补齐 MA5/MA10
