Feature Request: Merge/Combine Multiple Apps into One

It would be extremely helpful to have the ability to combine multiple existing Base44 apps into a single new project. Currently, the only option is to duplicate individual apps, but there's no way to merge them together.

Use case: I built 3 separate resource apps for my military base (a roommate finder, rides board, and marketplace). My leadership now wants them combined into one unified app and expanded across multiple bases. Without a merge feature, I have to manually recreate everything from scratch in a new app.

Proposed feature: Allow users to select 2 or more existing apps and merge them into a new combined project, bringing over the pages, entities, and logic from each.

This would save enormous amounts of development time, especially for users who started with smaller scoped apps that later need to be consolidated.
