fix(test): repair test infrastructure and mock fixtures (#281)

* fix(test): repair test infrastructure and mock fixtures

- Add test/__init__.py for proper test collection
- Fix ConfigManager instantiation to use config_path parameter
- Route schedule config through config_service mock
- Update mock to match get_raw_file_content endpoint change

Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

* fix(test): correct get_main_config assertion per CodeRabbit review

The endpoint calls load_config(), not get_raw_file_content('main').
Also set up load_config mock return value in the fixture so the
test's data assertions pass correctly.

* fix(test): correct plugin config test mock structure and schema returns

- Plugin configs live at top-level keys, not under 'plugins' subkey
- Mock schema_manager.generate_default_config to return a dict
- Mock schema_manager.merge_with_defaults to merge dicts (not MagicMock)
- Fixes test_get_plugin_config returning 500 due to non-serializable MagicMock

* fix(test): use patch.object for config_service.get_config in schedule tests

config_service.get_config is a real method, not a mock — can't set
return_value on it directly. Use patch.object context manager instead.
