- rbac_utils.py: change feature_name from str to Literal["agents", "vector_stores"]
so typos are caught by type checkers at import time
- proxy_setting_endpoints.py: extract _RUNTIME_GENERAL_SETTINGS_FLAGS as a module-level
constant, replacing duplicated inline lists in get_ui_settings and update_ui_settings
- test_vector_store_rbac.py: remove try/except pattern that silently swallowed non-403
HTTPExceptions; tests now let any unexpected exception propagate as a test failure
