## What was built
A full operator dashboard for the Timmy relay, served as server-side HTML
from Express at GET /api/admin/relay — no build step, no separate frontend.
Follows the existing ui.ts pattern with vanilla JS.
## New API endpoint
GET /api/admin/relay/stats (added to admin-relay.ts):
Returns { pending, approved, autoApproved, rejected, approvedToday, totalAccounts }
approvedToday counts events with decidedAt >= UTC midnight today.
Uses Drizzle groupBy on relayEventQueue.status + count(*) aggregate.
Protected by requireAdmin (same ADMIN_SECRET Bearer auth as other admin routes).
## Admin panel (admin-relay-panel.ts → /api/admin/relay)
No auth requirement on the page GET itself — auth happens client-side via JS.
Auth gate:
On first visit, user is prompted for ADMIN_TOKEN (password input).
Token verified against GET /api/admin/relay/stats (401 = wrong token).
Token stored in localStorage ('relay_admin_token'); loaded on boot.
Logout clears localStorage and stops the 15s refresh timer.
Token sent as Bearer Authorization header on every API call.
Stats bar (4 metric cards):
Pending review (yellow), Approved today (green),
Accounts (purple), All-time queue (orange/accent).
Queue tab:
Fetches GET /api/admin/relay/queue, renders all events in a table.
Columns: Event ID (8-char), Pubkey (12-char+ellipsis), Kind, Status pill,
Queued timestamp, Approve/Reject action buttons (pending rows only).
Auto-refreshes every 15 seconds alongside stats.
Approve/Reject call POST /api/admin/relay/queue/:id/approve|reject.
Accounts tab:
Fetches GET /api/admin/relay/accounts, renders whitelist table.
Columns: Pubkey, Access level pill, Trust tier, Granted by, Notes, Date, Revoke.
Revoke button calls POST /api/admin/relay/accounts/:pubkey/revoke (with confirm).
Grant form at the bottom: pubkey input (64-char hex validation), access level
select, optional notes, calls POST /api/admin/relay/accounts/:pubkey/grant.
Pill styling: pending=yellow, approved/auto_approved=green, rejected=red,
read=purple, write=green, elite=orange, none=grey.

## Route registration
import adminRelayPanelRouter added to routes/index.ts; router.use() registered
between adminRelayQueueRouter and demoRouter.
## TypeScript: 0 errors. Smoke tests:
- GET /api/admin/relay → 200 HTML with correct <title> ✓
- GET /api/admin/relay/stats (localhost) → 200 with all 6 fields ✓
- Auth gate renders correctly in browser ✓
