Subject: [PATCH] fix: guna PHP PDO untuk semak MySQL dalam entrypoint
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

mysqladmin resolve host.docker.internal ke IPv6 dahulu — MySQL Windows
tidak dengar pada IPv6, menyebabkan loop tak berakhir dan 502 pada Nginx.
PHP PDO guna IPv4 terus dan berjaya sambung.
