refactor(gui): refactor chat coding panel to use new FrontendCodeView class

The commit introduces a new class `FrontendCodeView` and refactors the `ChatCodingPanel` to use it. The `FrontendCodeView` simplifies the code by combining two panels (`WebBlockView` and `CodeBlockView`) into a single panel. The refactoring also removes duplicate code and improves the readability of the `ChatCodingPanel`.
