feat: add validation for invalid status code entries in channel modal

- Introduced a new function to collect invalid status code entries from the status code mapping.
- Updated the EditChannelModal to display an error message if invalid status codes are detected.
- Enhanced localization files to include new error messages for invalid status codes in multiple languages.
- Removed unused styles from the RiskAcknowledgementModal for cleaner UI.
