Summary: Added NetStore to create custom applications

I added an application that allows you to create your own custom applications. I will use this Store to build additional apps myself for niche use cases (e.g., Docker management or local server containers) that will be fetched directly from GitHub.

Key features:

• Custom Routes: Register your own custom backend routes.
• Frontend: Build and design your own user interface.
• Local Code: Execute custom code on the local server.

IMPORTANT: DO NOT USE NETSTORE IN PRODUCTION OR DEPLOYMENT ENVIRONMENTS. IT IS CURRENTLY NOT SECURE.
If you choose to use it anyway, you do so at your own risk. It’s on the dev Branch. I’d recommend to use it only in your local Network
