fix(ci): apply ruff format and suppress vulture containment_path

Reformat features/steps/resource_handler_project_access_1444_steps.py
and src/cleveragents/resource/handlers/_base.py to satisfy ruff format
check (complex slice spacing, collapsing single-f-string assert parens).

Add containment_path to vulture_whitelist.py — the parameter is
required by the ResourceHandler.project_access interface (spec
§21691-21698) but is intentionally unused in stub implementations
that raise NotImplementedError.
