🐛 fix(oracle): 修复 Oracle/Dameng 打开表时缺少 schema 前缀导致 ORA-00942

- 问题根因：GetTables 在 dbName 为空时走 user_tables 分支返回纯表名，下游 SQL 缺少 owner 前缀，引用未授权 schema 的表时报 ORA-00942
- SQL 修复：user_tables 分支改用 USER 伪列拼接 owner，确保始终返回 OWNER.TABLE_NAME 格式
- 驱动兼容：列别名用双引号包裹强制大写（AS "OWNER" / AS "TABLE_NAME"），避免不同驱动返回不一致 case 导致 row map 取值失败
- 边界保护：增加 TABLE_NAME 为 NULL 的跳过逻辑，避免污染表名输出
- 达梦对齐：DamengDB.GetTables 同步修复，保持与 Oracle 实现一致
- 测试覆盖：新增 3 个回归用例（all_tables 路径、user_tables 路径、NULL 值跳过），扩展 recording driver 支持 mock 任意查询结果
