scripts cache issue in test_dev_api_settings.py

(no _available_vram/_reserved_vram); drop deepest-queue VRAM-gating
ordering assertion (LocalScheduler is FIFO, not priority-gated);

budget assertion to not depend on shared pytest tmp dir state
- test_dev_api_settings: patch path functions (_resume_path, _search_prefs_path,
