Add dust threshold error handling and localization

Introduces a new InfoSheetType for dust threshold errors and updates error handling in transfer and info sheet flows to support it. Refactors ChainCoreError to simplify dust threshold representation and error mapping. Updates localization strings for dust threshold errors and adds a new 'no data available' message in all supported languages.
