Add an admin status freshness line using StatusDot on the admin page

[mikewheeleer]

Show a last-checked freshness line on the admin pause page

Description

src/app/admin/page.tsx loads /api/v1/admin/status and shows a StatusDot for the paused/active state, but it gives no indication of when that status was last fetched — so an operator cannot tell a freshly-loaded "active" from a stale one after the tab has been open for a while. This issue adds a "Last checked " line using TimeAgo, updated on each successful status load.

Requirements and context

• Repository scope: Agentpay-Org/Agentpay-frontend only.
• Track the timestamp of the last successful load() and render it via TimeAgo near the StatusDot.
• Do not interfere with the latest-wins status guard or the ConfirmDialog/toggle flow; only add the freshness line on successful loads.
• Keep the role="alert" error path and the pending/disabled toggle behaviour intact.
• Do not introduce polling (that is tracked elsewhere); update only on explicit/initial loads.

Suggested execution

• Fork the repo and create a branch
• git checkout -b enhancement/admin-status-freshness-line
• Implement changes
  • Write code in: src/app/admin/page.tsx; reuse src/components/TimeAgo.tsx.
  • Write comprehensive tests in: extend src/app/admin/page.test.tsx — assert the freshness line updates after a successful load and is not set on error.
  • Add documentation: note the freshness line in README.md.
  • Validate the line is associated with the status region for assistive tech.
• Test and commit

Test and commit

• Run npm run lint, npm run typecheck, npm test, and npm run build.
• Cover edge cases: first load, reload after a toggle, and a failed status load.
• Include the npm test output.
