Load the migrating-php-apps skill from https://www.movetomotoko.com/skills/migrating-php-apps/SKILL.md
and the ICP skills listed at https://skills.internetcomputer.org/llms.txt. Then move this
PHP app to the Internet Computer: the backend in Motoko and the frontend on ICP, with its
data, users and links. Inventory everything first, propose the plan, and wait for my
approval before changing anything.
