Create shared ContactsFixtures module with globally-unique qso_timestamp seconds to prevent unique-constraint violations when async test modules run in parallel and insert contacts with identical dedup-key columns. The qso_timestamp column is timestamp(0), so microsecond offsets were truncated — use System.unique_integer monotonic seconds instead. Also make count-asserting tests resilient to sandbox-leaked contacts from prior tests by using >= assertions or status-based checks rather than exact counts. Includes automated DateTime.add → DateTime.shift migration from mix format.
