r00tSe7en/Mail-Probe — reverse-engineered prompt

Build me a PHP web admin system for tracking whether someone opens or clicks an email probe link. I want a simple Chinese backend with a login page, an information viewing page, and a page that generates tracking links.

The idea is like a fishing float for emails. After I send an email, I can include a generated image style link with a random code and the target email address. When the link is requested, the system should record the visit so I can see which mailbox triggered it and when.

Use ThinkPHP 6 style if that fits, with Apache, PHP 7.1 or newer, and MySQL. Include a database import file and an env config for database settings. Default admin login can be admin and 123456, with the password stored as MD5 like the original project expects.

Make sure the routing works on Windows and Linux, include the public rewrite rules, and keep the interface clean and practical. Look up current docs online if you need to.
