feat(i18n): add saveFailed message and dimensionRatesMixedHint to locale files

- Updated English, Nepali, and Chinese locale files to include a new message for "Failed to save configuration".
- Added a hint for mixed rebate rates within the same dimension to enhance user understanding.
- Improved internationalization support across multiple locales for better user experience in the admin interface.
