Delete interactive models

[soerendomroes]

We have a whole lot of interactive models, which I added because I wanted to document them at some point. Now, I however think that most of them are unnecessary.

[Copilot]

Pull Request Overview

This PR removes multiple interactive example models that were originally created for documentation purposes but are now deemed unnecessary. The deletion focuses on interactive layout examples for both layered and rectpacking algorithms.

• Removes 22 interactive model files demonstrating various layout scenarios
• Cleans up documentation that was specific to certain editors (KIELER, Keith)
• Retains one file with updated documentation that removes editor-specific constraints
