refactor: introduce CheckContext to encapsulate client, config and resource manager

- Remove client field from CheckConfig class
- Create CheckContext class that encapsulates SCIMClient, CheckConfig, and ResourceManager
- Update @checker decorator to create and pass CheckContext instead of separate objects
- Simplify function signatures from (conf, model, resources) to (context, model)
- Update all conf.client usages to context.client throughout codebase
- Update all test files to use new CheckContext structure
- Maintain 89% test coverage with all tests passing

This eliminates the need to pass conf and resource_manager objects separately,
providing better encapsulation and a cleaner API.
