Section layout improvement

[Dammshine]

The Issue

The current implementation of Tabs/Tab uses frontend pattern compared to the rest of the debugger visualizer code. We might consider tp re-implement Tabs/Tab either inside development-mode-src or move the original implementation . To increase maintainability and add new featurs on top.

Stages

Remove Tabs, Tab to a way that it’s more clear how to use both class. and customizable.

Improve the boarder of layout. To more clear, and consistent throughout the code. (I expect this to be a big refactoring, you might consider to design a container class for this job)

Improve layout of sections, add feature to allow use dynamically adjust the boundry of each sections.
