Admin Peers page — WireGuard peer management UI tests.

Scenarios:
  8. Create peer via UI → success toast (password modal removed — admin enters it)
  9. Delete peer via UI → peer disappears from the table
 10. WireGuard page port check badge renders (Open / Blocked / Checking)

Key selectors confirmed from Peers.jsx:
  - "Add Peer" button: button with text "Add Peer" (Plus icon + text)
  - Name input: input with placeholder "mobile-phone"
  - Password input: type="password" autocomplete="new-password"
  - Submit button: button text "Add Peer" (type="submit" inside the form)
  - Delete button in peer row: button title="Remove Peer" (Trash2 icon)
  - Confirmation: window.confirm() — Playwright auto-accepts dialogs
