ChatBots Two Columns UI Fix

Expands ChatGPT conversation column to use full width on large screens and reduce wasted white space.

This masculine extension reduces space waste on major screens - placing prompt & response next to each other for better experience on bigger screens. Some other UI glow up is included. The focus is my own experience, therefore Perplexity AI, Claude, ChatGPT and Qwen have better support, but changes were made for DeepSeek, Gemini (that one was most pain) and Grok. Feel free to submit PRs improving the layout especially if it doesn't work best on your own device. We do not log the conversations. The extension should not make any external connections and does not save any data private or other. I only wish address what is, frankly, terrible UI design.
