Summary

Adds a timelock action queue panel to the admin dashboard for issue #1014.

Changes

• Adds pending queue and executed/cancelled history views with live ETA countdowns.
• Adds full JSON parameter details in an accessible dialog.
• Gates cancellation on configured admin access, pending status, and the API-provided cancellation deadline; refreshes queue/history after cancellation.
• Adds typed service methods and focused tests for API normalization, countdown, detail display, and cancellation gating.

Backend integration required

This client repository does not contain a timelock contract ABI, contract address/configuration, or the backend route implementation. The panel currently expects authenticated endpoints GET /admin/timelock/actions/pending, GET /admin/timelock/actions/history, and POST /admin/timelock/actions/:id/cancel. Queue records must include id, type, params, eta, status, and cancellable; cancellation-window metadata may be supplied as cancellationDeadline. The cancel endpoint must enforce admin authorization and the on-chain cancellation window and submit the contract transaction. Marked draft until that API/contract integration is confirmed.

Verification

• pnpm vitest run src/services/__tests__/admin.service.test.ts src/components/admin/__tests__/TimelockQueuePanel.test.tsx (17 passed)
• pnpm lint (passes with two existing warnings in BatchTradePanel.tsx)
• pnpm build (passes)
• pnpm test currently has 137 failures in unrelated existing suites; 285 files pass.

Closes #1014
