debug: Add min API that allows to get/set camera from dbg console.

[MisterGC]

Motivation and scope: In the scope of testing scalability/performance of erdblick, I needed a way to always use the same location for my tests. I have thought about different ways how to achieve this with the current state of implementation. My conclusion was that it would be good if there'd be a component that allows me to add debug functionality easily but without polluting the regular code base, therfore I suggest to introduce the ErdblickDebugApi class.

Testing: To test this API, you can follow these steps using your browser's developer console:

1. Get Current Camera Information

   const cameraInfo = window.ebDebug.getCamera();
   console.log(cameraInfo);

2. Set Camera Position Using Previous Information

   window.ebDebug.setCamera(cameraInfo);

Simply copy the output from getCamera() and use it as input for setCamera(). This allows you to share and reuse camera positions across different sessions effortlessly.

I think this might be a good solution, also to toggle the loading indicator dots on/off.

What do you think about directly adding a function like flyToMunich? Imo, we can make this class as convenient as we like.

Yes, I agree, it's a development tool and small utilities that ease debugging and/or profiling should be directly added. If the API is fine for you, I'd say we should merge this PR and every dev can add functionality on demand.
