refactor(web): extract useCopyToClipboard hook to reduce duplication

[SherlockShemol]

Closes #31314

Summary

I noticed the copy-to-clipboard logic was duplicated in 4 different components, so I extracted it into a reusable useCopyToClipboard hook.

Changes:

• Created hooks/use-copy-to-clipboard.ts with shared logic
• Refactored CopyIcon, CopyFeedback, CopyFeedbackNew, and InputWithCopy to use the new hook
• Reduced ~67 lines of duplicate code

Test plan

• pnpm lint:fix passes
• pnpm type-check:tsgo passes
• Manual testing: verify copy functionality works as before in each component

Summary of Changes

Hello @SherlockShemol, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the codebase by extracting redundant copy-to-clipboard functionality into a single, reusable custom React hook. This change streamlines the implementation of copy features across various UI components, making the code cleaner, more modular, and easier to maintain.

Highlights

• New useCopyToClipboard Hook: A new custom React hook, useCopyToClipboard, has been introduced to centralize the logic for copying text to the clipboard and managing the copied state.
• Component Refactoring: Four components (CopyFeedback, CopyFeedbackNew, CopyIcon, and InputWithCopy) have been refactored to utilize this new hook, removing duplicated clipboard handling logic.
• Code Reduction: This refactoring effort has successfully reduced approximately 67 lines of duplicate code across the codebase, enhancing maintainability.

Code Review

This pull request is a great initiative to reduce code duplication by extracting the copy-to-clipboard logic into a reusable useCopyToClipboard hook. The refactoring is clean and improves maintainability. However, the new hook has a few issues: it introduces a functional regression for one of the components, has a performance issue due to an unstable dependency, and lacks cleanup for debounced functions which could lead to state updates on unmounted components. I've provided detailed comments and suggestions to address these points and make the hook more robust.
