chore: psycopg 改用 binary extra，精简 Dockerfile 的 apt 依赖

psycopg[binary] 替代并列声明的 psycopg + psycopg-binary。上游的
binary extra 是 psycopg-binary==<同版本> 的精确 pin，而原来两条各自
带范围，没有东西保证它们同步——单独升级其中一个就可能凑出上游没测过
的组合。解析结果不变，requirements.txt 只多了 extra 自带的
implementation_name != 'pypy' 标记。

apt 依赖从 10 个降到 4 个：
- curl / unzip / openssl：全仓库零引用。解压走 Python zipfile，
  健康检查走 xmlrpc，openssl 装的是 CLI 而 Python 要的是 libssl
- libpq5：psycopg_binary.libs 自带 libpq.so.5.18，容器内实测
  psycopg.pq.__impl__ == binary
- libjpeg62-turbo：pillow.libs 自带 libjpeg.so.62
- zlib1g：base 镜像的 CPython 已经带着

保留 ca-certificates（smtplib 走 TLS 时读系统信任库，不是 certifi）、
clang-format（submission/utils.py 调用）、passwd（entrypoint 建账号）、
supervisor。
