🎗️ Full structure revision with major optimizations

I've finally found the bug that prevented to update the project to Vitepress 1.5.0.

Also I've removed all auto-imports as the code is much more readable and easy to think of with explicit imports.

Cleaner config and less abstractions.

Content moved from src to content folder.

💿 Vertical cards and stone bg

Better visual organization and unified cards for any product photo size.

Basic static site shop

First release as a starting point for next phase of the shop development. Should we transition to Nuxt for more dynamic shop?
