🎨 Palette: Add accessible focus state and ARIA label to Remove Image button

[MacTechIN]

💡 What:

• Added an explicit aria-label to the "Remove Image" icon-only button in the ImageUploader component.
• Added aria-hidden="true" to the inner Lucide <X /> icon so screen readers don't read it out redundantly.
• Added explicit keyboard focus states (focus-visible:ring-2 focus-visible:ring-red-500 focus-visible:ring-offset-2 focus-visible:outline-none) to ensure the focus ring is clearly visible and not clipped by the container edge.
• Logged a critical learning regarding absolute positioned overlay buttons and focus rings in .Jules/palette.md.
• Cleaned up duplicate imports/interface declarations in the file.

🎯 Why:

• The previous "Remove Image" button relied only on a title attribute, which is insufficient for proper screen reader accessibility.
• Because it is absolutely positioned at the edge of the container, native focus rings can appear cut off or be missing entirely in some browsers. Using ring-offset pushes the ring out slightly, ensuring keyboard users can clearly see when the button is focused.

📸 Before/After:
(Visual changes relate to the keyboard focus state only; the default resting state remains identical).

• Before: Tabbing to the button may show a faint or clipped focus ring. No explicit ARIA label.
• After: Tabbing to the button shows a clear, unclipped red focus ring that matches the destructive intent of the button.

♿ Accessibility:

• Improved screen reader context (accessible name).
• Improved keyboard navigation visibility.

Code Review

This pull request cleans up duplicate interface definitions in ImageUploader.tsx and improves the accessibility of the "Remove Image" button by adding focus ring styles, an aria-label, and hiding the inner icon from screen readers. It also adds a learning document about focus rings on absolute positioned overlay buttons. The reviewer suggested explicitly setting the button's type to "button" to prevent unexpected form submissions.

Explicitly set the type attribute of the button to 'button'. By default, button elements inside a form default to type 'submit', which can cause unexpected form submissions when the user clicks the 'Remove Image' button.
