Fix: Improve Code Pasting Functionality for Code Blocks

[SwapnilChand]

Description:
Currently, when pasting code blocks into the application, users experience significant formatting issues. Instead of pasting the intended code, the application often displays an HTML representation, which disrupts the intended structure and readability. Additionally, pasting code can break the width of the code block element, making it difficult to read and edit.

Expected Behavior:
Plain Text Pasting: Pasting should only include text without any HTML formatting. This would allow for a cleaner and more predictable outcome.
Color Handling: The application should support syntax highlighting or color coding when pasting code blocks to enhance readability and maintain context.

Steps to Reproduce:
Copy a block of code from an Integrated Development Environment (IDE) such as VSCode
Paste it into the application.
Observe that instead of the expected formatted code, an HTML version appears, and the width of the code block is altered.
