Adds CVTuning to CVState, populates defaults from existing file-scope constants in cv_init, and introduces config_load_tuning/config_save_tuning backed by the doorcounter NVS namespace. No runtime behavior change yet; CV code still reads the existing constants (Task 2 will migrate reads). Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
