feat: inline copy feedback for code blocks

[cnaples79]

Summary

• replace toast-based copy confirmation with inline feedback on the code block button
• reuse the existing copy hook to toggle button text/icon to "Copied" after clicking

Rationale

• keeps feedback adjacent to the action and removes the global toast dependency (accessibility and clarity)

Changes

• CodeBox now uses useCopyToClipboard state for inline status and no longer calls NotificationProvider
• BaseCodeBox accepts an optional copied flag to swap the copy icon for a checkmark

Fixes #8357

Looks good, thanks! Could you please run prettier on apps/site/components/Common/CodeBox.tsx to fix CI?

I don't think you should add this prop, you can change the buttonText prop to be of type ReactNode and pass the icon directly with the text.

I believe you can remove the whole source of NotificationProvider, including tests, stories and remove it from the Layout too. Which would also allow you to remove the "use client" from the layout. (I think?)
