feat(param_check): significance layer — a focus list of config-value outliers

Rank findings by significance: config_value (setpoint/hysteresis/time/threshold —
an odd device is usually a real mistake) vs config_flag (mode/type) vs label
(per-room text, often intentional). New focus list surfaces the config-value clear
outliers first. On a real 275-device project this turns 422 raw outliers into a
9-item focus that includes the thermostats whose init-setpoint differs from their
siblings. Multilingual name hints (EN/DE/RU). Test updated.
