Ai Assistant minor issues to fix before main release

[STetsing]

• Accept reject function name is removed on accept sporadically
• Accept / reject not shown completely. This should be relative to the user window size
• Exiting file in Accep/reject mode, then commit back is similar to accept where the user never accepted the suggestion
• Markdown too fat sometime, bullet points are misaligned
• Setting assistant click outside the radio button field does not close the field
• On AI generated code, .deps folder is unrolled. This is painful
• Scrolling down do not happen automatically on streaming results. The UI elements are displaced or shifted down
• AI Window is sometimes resized randomly
• Write provider name instead of Set Assistant
• The AI icon in the left isn't centered
• Integrate with accept/reject
