fix(omg-pay): 修复 PosOrderOmgPaymentMapper.xml 原始 < 致应用启动失败(SAXParseException L66)

selectLeakOrderDdIds 的 SQL 用了未转义的 <= 和 <>:
  AND create_time <= #{graceCutoff}   (L66)
  AND (o.state IS NULL OR o.state <> 4)
XML 解析报 "The content of elements must consist of well-formed character data or markup"
(line 66 col 32) → SqlSessionFactory 起不来 → 整个应用启动失败。

mvn compile 不校验 mapper XML 内的 SQL,故一直 BUILD SUCCESS、运行时才炸。

修复:转义 &lt;= / &lt;&gt;(>= 也规整为 &gt;=)。python XML 校验通过;
全量 grep 所有 mapper 确认无其它原始 <(其余命中均为合法 >= 或已转义 &lt;)。
