AI-Powered Fixes get a Beta badge and smoother toggling

This update makes interacting with our AI remediation tools more seamless and clear. We've addressed the issue where the AI remediation category toggle wasn't working as expected, so switching this feature on and off now happens smoothly and reliably.

**Enhanced customization options**
You can now personalize the AI remediation experience more easily thanks to new fields that let you tweak button texts, form labels, links, and decorative images. This means the AI-powered fixes can feel more tailored to your workflow and preferences.

**Highlighting AI as Beta**
Since AI capabilities are evolving, we've added a Beta badge to the AI-Powered Fixes category. This helps communicate that these features are fresh and improving, inviting your feedback while you explore what they can do.
