Add an integration test for the verifier reject flow updating queue and history

[1nonlypiece]

📌 Description

The existing verifier integration test covers approve. A complementary
integration test should drive the reject path from ValidationDetail through the
verifier store, asserting the task leaves the pending queue and lands in history
as rejected with notes.

🎯 Requirements and Context

• Open a task, check criteria, reject with notes, confirm in modal.
• Assert the task is removed from pending and present in history as rejected.
• Assert the notes are persisted on the history record.

🛠️ Suggested Execution

1. Fork the repo and create a branch

git checkout -b test/verifier-reject-flow

2. Implement changes

• Extend src/pages/__tests__/verifierFlow.integration.test.tsx.

3. Test and commit

• Run npm test.
• Cover edge cases: reject without notes, criteria gate blocks reject if
  required, history reflects status, queue count decremented.

Example commit message

test: verifier reject flow queue-to-history integration coverage

✅ Guidelines

• Minimum 95% test coverage on the new/changed lines.
• RTL-based integration assertions.
• Timeframe: 96 hours.
