Subject: [PATCH 1/3] feat(app): add duplicate template and test query for
 Widget Lab
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add "Duplicate" button (Copy icon) on template cards — creates a copy
  with "(copy)" suffix via existing createTemplate mutation
- Add "Test Query" button (Play icon) on templates that have a query
  and connection — executes the query via /api/query and shows
  success/error result
- Test query button disabled while running, shows loading state

Closes #270

Subject: [PATCH 2/3] chore: exclude Next.js page components from SonarCloud
 coverage

Page components (app/**/page.tsx) are UI-heavy React Server/Client
components that require full browser mounts to test. Their logic is
covered via E2E tests, not unit tests. Excluding them prevents false
coverage gaps on PRs that modify page-level handlers.

Subject: [PATCH 3/3] fix(app): add fetch timeout, replace alert with inline
 feedback, dedup copy suffix

- Add AbortSignal.timeout(30_000) to handleTestQuery fetch call
- Replace all alert() calls with toast notifications (useToast from @neoboard/components)
- Handle TimeoutError specifically with a dedicated message
- Add handleDuplicate with (copy) suffix deduplication via regex strip
- Add onSuccess/onError callbacks to createTemplate.mutate in handleDuplicate
