test: FakeChangeLog and SchemaFixture instead of repeated mocks (T2)

- tests/Support/FakeChangeLog extends ChangeLog: records record()/recordPartial()
  calls, increasing ids, optional failure; new FakeChangeLog(id) / partialsOnly() /
  any(id) / forbidden() mirror what the replaced mocks allowed. assertRecorded() /
  assertPartials() check count and the named arguments. Calls a fake does not allow
  throw and are also verified in TestCase::tearDown (one assertion per test that
  uses a fake), so swallowed change-log calls still fail like a never() expectation.
- All ChangeLog mocks of ability/integration tests replaced (the admin tests that
  stub query/purge/clear keep their mocks); expectException tests that checked the
  partial log now catch and assert.
- SchemaFixture::managed(?divi) replaces the 21 isManaged-only ContentSchema mocks;
  DiviFixtures::schema() uses it.
Tests 1397 -> 1404 (FakeChangeLogTest); no test has fewer assertions.
