Build me a small PHP website for managing and displaying boundary information, with a simple admin style page where I can edit the boundary visually and save it to the database.

I want a clean home page, a boundary editor page, and basic support for uploading and showing files or images from an uploads folder. Please make it work with the existing database setup and SQL files, and keep the app easy to run on a standard PHP server. If there are any missing details, use sensible defaults and look up current docs online if you need to.

Make the interface simple and mobile friendly, with forms that are easy to use and clear feedback when something is saved or uploaded successfully. If the project already has some API or existing data structure, keep it working and wire the pages into it instead of starting over.
