chore(FR-2917): remove unused Alert import in VFolderNodes.tsx

[ironAiken2]

Resolves #7471(FR-2917)

Summary

Removes an unused Alert import from react/src/components/VFolderNodes.tsx.

Alert was left in the antd import after its last usage was removed (in 0ca1f8b1d, FR-2819 / #7370) but the import line was not cleaned up. It is now dead.

Why split out

This is not part of any feature work. It surfaced because the strict pre-commit hook (eslint ./src --max-warnings=0 via lint-staged) lints the whole react/src tree, so this pre-existing no-unused-vars warning on main blocks unrelated commits. Splitting it into its own one-line PR keeps the FR-26 PR (#7455, stacked on top of this) scope-clean while unblocking the strict hook.

Changes

• react/src/components/VFolderNodes.tsx — drop Alert from the antd import (no behavior change; the symbol had no remaining references).

Test plan

• eslint ./src --max-warnings=0 no longer reports the 'Alert' is defined but never used warning.
• No runtime behavior change (import-only removal).
