Add tests for Services, List Modules, Chart Modules, and AutoComplete handlers

[boris-unckel]

This PR fills 23 previously empty test stubs (from commit a813962 "Add minimal test scripts for every class") with 137 new test methods covering core services, list modules, chart modules, and autocomplete request handlers.

All tests use the existing TestCase infrastructure with SQLite in-memory database and demo.ged fixture. No changes to production code.

Known issue found during testing

AutoCompleteCitationTest::testHandleReturnsJsonForValidSource is marked as skipped. During test development, FamilyFactory::mapper() was observed returning null for families whose members are privacy-restricted, causing a fatal error in the citation autocomplete handler.
This appears to be a pre-existing issue, not introduced by these tests. I can file a separate issue if helpful.

Test data

All tests use the bundled demo.ged fixture via $this->importTree('demo.ged'). No additional test data files are needed.
