fix(ci): docker compose --env-file 仅 release/next 启用，prod 完全不动

前一版改动会让 master→prod 部署也走 --env-file .env / Pre-deploy 强制 .env 检查，
若 prod 部署机（172.17.16.14）没准备 .env 会直接 fail，破坏现有 prod 部署。

改动：
- Initialize 阶段按分支设置 COMPOSE_ENV_FILE_ARG：
    release/next → '--env-file .env'
    master/其他   → ''
- 所有 docker compose 命令用 ${env.COMPOSE_ENV_FILE_ARG} 拼接
- Pre-deploy Check 的 .env 文件存在性校验仅 release/next 触发

行为：
- master → prod 完全沿用历史路径（docker-compose.core.yml 内嵌默认值兜底）
- release/next → release 强制注入 .env（环境隔离 + 凭据脱离 git）
