migrate.sh 支持 DSN 与可选客户端路径

Browse Source 
生产的宝塔机器把数据库配置放在一个 Go 风格的 IM_DB_DSN 里，而不是 compose
的那组 MYSQL_* 变量；同机自带的 mysql 客户端又缺 caching_sha2_password 插件，
连不上 MySQL 8.4。脚本原先把主机写死成 compose 的服务名 mysql，在非 Docker
环境用不了。

现在 MYSQL_HOST/MYSQL_PORT/MIGRATIONS_DIR/MYSQL_CLIENT 都可覆盖，未设置
MYSQL_USER 时从 IM_DB_DSN 解析；显式的 MYSQL_* 仍然优先。默认值保持 compose
原样，Docker 路径行为不变。
