feat(autofix): Integrate setup and summary into Autofix drawer

[roaga]

Adds the issue summary and the Autofix set up into the Autofix drawer (the latter won't be seen by users yet since the banner is still set-up-gated).

In a future PR, I'll move the entry point to this drawer to the new Solutions Hub, remove the old entry points, integrate the Resources & Solutions doc links, and use the hide AI setting.
