Subject: Add rendered/plain text toggle for response views

Add an Eye/EyeOff toggle button to switch between rendered markdown and
raw plain text in all three response locations: main response panel,
expanded response modal, and Quick Chat messages. Useful for copying
raw text without formatting artifacts.
