Split Available Experiments into Editor and Admin sections

[jeffpaul]

What problem does this address?

Update the AI Experiments settings screen to group available experiments into two clear sections: Editor Experiments and Admin Experiments. This improves clarity for users by distinguishing features that appear in the editor from tools intended for site administration, exploration, or developer experience.

What is your proposed solution?

Proposed structure...

Editor Experiments (in this order):

• Title Generation
• Excerpt Generation
• Content Summarization
• Image Generation
• Alt Text Generation

Admin Experiments:

• Abilities Explorer

Hi! I'd like to work on this issue. I'll split the Available Experiments section into Editor Experiments and Admin Experiments by adding a category field to the experiment metadata and grouping them accordingly in the settings page.
