test(a2h2a): add end-to-end test for approval flow

Adds a test script that validates the entire A2H2A approval process, from ticket creation to final verification in Firestore.

- The server now supports a `test_mode` flag to facilitate testing.

- The test verifies ticket creation, review page access, approval, final ticket status, and audit log creation.
