fix: Sidebar: Copy Payload - tooltip is wrong

[cursor]

Summary

Fixes the incorrect "Copy Link" tooltip on Copy Payload buttons. The tooltip now correctly shows "Copy" instead of "Copy Link" when hovering over the copy-payload button.

Changes

• SidebarEventItem.tsx: Changed tooltip from "Copy Link" to "Copy" on the payload tab copy button and the payload modal copy button.
• ChainItem.tsx: Changed tooltip from "Copy Link" to "Copy" on the payload tab copy button.

The actual "Copy Link" tooltip on the execution link copy button in SidebarEventItem.tsx remains unchanged, as that correctly copies a link.

Closes #1285

@cursoragent If this button is the same for all, with same style too. Please put this in a separate component

Done. Here's a summary of the changes made in response to the review feedback:

• Created a new CopyPayloadButton component (web_src/src/ui/componentSidebar/CopyPayloadButton.tsx) that encapsulates the copy-to-clipboard logic, the "Copied!" tooltip feedback with timeout, and the button rendering. It supports two variants: icon (icon-only, default) and labeled (icon + "Copy" text), with configurable iconSize and className props.

• Replaced all 4 duplicated instances across SidebarEventItem.tsx (2 instances) and ChainItem.tsx (2 instances) with the new shared component. Cleaned up the now-unused payloadCopied state, copyPayloadToClipboard callback, and in ChainItem also copyToClipboard and the useCallback import.

• TypeScript compilation and Vite build both pass cleanly. Changes are committed and pushed to the PR branch.
