Update image metabox copy

[jeffpaul]

Is your enhancement related to a problem? Please describe.

This is the current state in an image attachment page: I would expect more users would understand "ClassifAI Image Processing" versus "Azure Computer Vision Scan" and "Rescan Alt Text" versus "Rescan Captions". Let's update this copy accordingly.

Describe the solution you'd like

• [ ] update metabox title to ClassifAI Image Processing
• [ ] update the rescan label to Rescan Alt Text
• [ ] update the scan label to Scan Alt Text
