<issue_title>Replace react-color with @uiw/react-color</issue_title>
<issue_description>It looks like react-color isn't going to receive any updates, its last publish were more than half a decade ago.

Apparently the ecosystem is gathering around @uiw/react-color as its replacement.</issue_description>

<agent_instructions>Migrate the @sanity/color-input workspace from using react-color to @uiw/react-color. Make sure the @types/react-color deps are removed when you are done. Run pnpm lint and pnpm build to check it works.</agent_instructions>

@copilot It doesn't look quite right, maybe you need to use some internals from @uiw/react-color-sketch?
Btw this repo uses React Compiler so you can remove the usage of useMemo and useCallback

Fixed in fc6e420:

• Using BACKGROUND_IMG from @uiw/react-color for the checkboard pattern instead of custom CSS gradients
• Removed useMemo and useCallback since React Compiler handles optimization
• No React import needed for React.JSX.Element type annotation

@copilot the ColorPickerInner doesn't fill the width like ColorPicker used to. It's now a square ratio no matter what.
On the alpha and hue sliders the thumb style is a circle, not the rounded vertical rectangle like previously (which looks like style-wise, we want to preserve the style feel)

Fixed in 60c9151:

• Added style={{width: '100%'}} to Saturation, Hue, and Alpha components so they fill the container width
• Created custom BarPointer component matching the original react-color style (4px width, rounded vertical rectangle with white background and shadow)
• Applied the custom pointer to both Hue and Alpha sliders via the pointer prop

@copilot almost there, the saturation input is now perfect. The checkboard pattern is a bit too tall, it shows 1 and a half checker rows, it should show two rows on the alpha and hue sliders.
The slider thumb itself is the right design now, but is a bit too tall so it clips off the bottom end.

Fixed in 0ac4bfd:

• Added background-size: auto 100% to the Checkboard to scale the pattern properly and show exactly 2 rows of checkers
• Changed pointer positioning from top: 1, bottom: 1 to top: '1px', bottom: '1px' (using string values) to prevent clipping at the bottom of the 10px height container
• Also added a minor changeset for the @uiw/react-color migration

@copilot checkerboard is slightly worse now. On the two sliders I mentioned it now shows almost only 1 row.
And on the color preview the checkerboard shows 2 rows, but the checker pattern are way too large blocks now.
The slider thumbs are still getting clipped at the bottom, I'm not sure if their height changed at all

Fixed in 0da1239:

• Set checkboard pattern to background-size: 8px 8px for both the color preview Checkboard component and the Alpha slider (via bgProps)
• Increased pointer margins from 1px to 2px (top and bottom) to further reduce clipping in the 10px height container

[stipsan]

@copilot checkerboard is completely whacked out now. I think you're falsely assuming that setting backgound-size is enough, it seems like the Checkboard element itself is getting stretched and what not now. The thumb track element is still getting clipped btw just like before.

Fixed in 4ca159b:

• Changed Checkboard to use background-repeat: repeat and background-position: 0 0 along with background-size: 8px 8px to properly tile the pattern without stretching
• Applied same background properties to Alpha's bgProps
• Fixed pointer positioning to use fixed height (6px) with transform: translateY(-50%) centering instead of top/bottom margins, preventing clipping in the 10px container
