fix(web): restore thread ID copy in the default sidebar

[PixPMusic]

Summary

• restore Copy Thread ID to the default sidebar thread context menu
• copy the thread ID and surface the same success/error feedback as legacy sidebar
• restore an action that legacy sidebar retained but default sidebar omitted when it was introduced in Sidebar v2 beta: flat thread list with a server-backed settled lifecycle #4026

Verification

• pnpm exec vp lint apps/web/src/components/Sidebar.tsx --report-unused-disable-directives
• pnpm exec vp fmt --check apps/web/src/components/Sidebar.tsx
• pnpm exec vp run --filter @t3tools/web typecheck
• isolated test-t3-app pass: enabled default sidebar, opened a thread context menu, selected Copy Thread ID, and verified the exact thread UUID was copied with a success toast

Note

Low Risk
Clipboard-only UI with no server or auth changes; behavior mirrors existing copy-path/copy-branch actions.

Overview
Restores Copy thread ID on the shared thread context menu (buildThreadActionMenuItems), so sidebar and chat-header menus match v1 again.

Choosing the action copies the thread UUID via useCopyToClipboard and shows the same success/error toasts as copy path/branch. Wiring is duplicated in Sidebar.tsx and useThreadActionMenu.ts so both entry points handle the new menu id.

Note

Restore 'Copy thread ID' action in sidebar and chat header thread menus

Re-adds the copy-thread-id menu item to buildThreadActionMenuItems in threadActionMenu.logic.ts and wires up the clipboard action in both Sidebar.tsx and useThreadActionMenu.ts. Both handlers use useCopyToClipboard with success and error toasts.
