test(fusion_claims,fusion_tasks): fix clone-test failures (future dates + seed-aware asserts)

Real install verified on the Westin clone; these were test-only bugs:
- Task-create tests hardcoded scheduled_date 2026-06-03, now in the past, which
  the base _check_no_overlap rejects ('Cannot schedule tasks in the past'). Use
  future dates (tz test pins a future July date so Toronto stays EDT for the
  9:00->13:00 UTC assertion).
- Service-rate resolver tests created rows with seeded codes (callout_standard_normal,
  per_km) -> UNIQUE(code) violation post-install. Assert against the seed instead.
