Fixes: 1) Fixed case sensitivity in region code normalization (lowercase regions); 2) Corrected translation file updates to match new string values. Extra: 1) Refactored middleware to normalize language codes to lowercase; 2) Added new locale paths for engine modules; 3) Improved consistency in translation keys and fallbacks.
