What is the proposed approach?

This PR fixes an issue where custom 'chatButtonStyle' width and height values were not consistently applied to the chat toggle button.

Previously, the button’s dimensions were effectively constrained by fixed values defined in 'ChatBotButton.css', which prevented developers from fully customizing the button size using the 'styles' prop.

To resolve this, I

• Removed the fixed 'width' and 'height' from 'ChatBotButton.css'
• Defined default dimensions (75×75) directly in 'ChatBotButton.tsx'
• Ensured that 'chatButtonStyle' values are spread after defaults so user-provided styles properly override them
