chore(deps): 引入 Flyway 数据库迁移管理

新增内容:
- 添加 flyway-core 依赖 (Spring Boot 2.7 管理版本 8.5.x)
- 新增 FlywayConfig.java — 适配动态数据源，手动指定主数据源
- 排除 FlywayAutoConfiguration，使用自定义配置
- application-dev.yml 添加 spring.flyway 配置
  - baseline-on-migrate: true (对现有表建立基线)
  - baseline-version: 0
  - locations: classpath:db/migration
- 新增 db/migration/V1__baseline_marker.sql 基线标记
- 新增 db/migration/README.md 使用说明

验证结果:
- ✅ flyway_schema_history 表已创建
- ✅ 基线 (version=0) 已建立
- ✅ V1 迁移已执行
- ✅ 服务正常启动

使用方式:
后续新增表或修改表结构，在 db/migration/ 创建 V2__xxx.sql,
V3__xxx.sql 等文件，启动时 Flyway 自动执行

+# Flyway 数据库迁移目录

+## 规范

+- 命名格式: `V{版本号}__{描述}.sql`
+  - 示例: `V1__init_schema.sql`, `V2__add_user_avatar.sql`
+- 版本号: 整数，递增，不可重复
+- 分隔符: 双下划线 `__`
+- 已有表: 通过 `baseline-on-migrate=true` 自动建立基线，无需手动迁移
+
+## 使用方式
+
+1. 新增表或修改表结构时，在此目录创建新的 SQL 文件
+2. 文件名中的版本号必须递增
+3. 启动应用时 Flyway 自动执行未执行的迁移
+
+## 注意事项
+
+- **不要修改已执行的迁移文件**
+- 生产环境部署前先在测试环境验证
+- `baseline-on-migrate=true` 仅在首次启用时生效
