fix(mdp): restore mdp_entity inbound defaults under CodeFirst | server 1.0.555

1.0.554 把 inbound_enabled / stale_guard_enabled 收口为 TINYINT + DEFAULT，
migration 与 verify 均 Success；但下一次启动时 SqlSugar CodeFirst
（EnableInitTable=true）按实体声明 `public int` 把它们改回 INT，其 ALTER
形态为 `alter table t change column c c int NOT NULL`——不带 DEFAULT 子句，
于是连带抹掉 DEFAULT，S1/S2 的 Error 1364 复现。

对照组证明了正确解法：inbound_max_rows 的类型本就等于实体声明的 INT，
CodeFirst 无差异可纠正、不生成 ALTER，其 DEFAULT 500 完整穿越了 CodeFirst
遍历。即：只要列类型与实体声明一致，CodeFirst 不重写该列，DEFAULT 存活。

故本批类型保持 INT，只补 DEFAULT。类型漂移（INT vs 契约 TINYINT）留 R2-B，
待 CodeFirst schema authority 定案后统一处理。

1.0.554 保持历史不变：不修改、不改 hash、不改 migration log、不重放。
其 inbound_max_rows 的 DEFAULT 500 成果保留，本脚本只对它做前置断言（G5），
若 500 丢失即判 SCOPE CHANGED 并中止，不顺手补。

实现要点：
- 逐列 target-state 比对，CONCAT_WS 拼子句，已正确的列真 no-op
- G6 类型守卫：两列必须已是 INT NOT NULL，否则中止，本脚本不自动改类型
- COLUMN_DEFAULT 比较用 NULL-safe <=>
- ALGORITHM=INSTANT（纯元数据，不重建表，无写阻塞），3307 实测 58ms
- 门禁前附可读诊断 SELECT（SIGNAL 不支持 prepared statement，条件成立时
  实际抛 1295 而非预期消息）

演练补上了上一轮的盲区——这次跑了真实 backend：
  SQL 执行 → 三列 int/0、int/500、int/1
  CodeFirst 完整遍历 285/284 → 三个 DEFAULT 全部存活
  重启再跑一次完整遍历 → schema checksum 逐位不变
  裸 INSERT 省略三列 → 落值 0/500/1
