Rebranding
- Renamed ZilPay to Bearby: Updated icons, i18n translations (en/ja/ko/ru/zh), manifest files (manifest_2.json, manifest_3.json), and package.json
Bug Fixes - Fixed Ledger eth_sign support: Added signEthMessage to LedgerController with automatic hex vs UTF-8 message detection, routing through the Ethereum Ledger app instead of the Scilla app. Updated SignMessagePopup to use the correct signing method for eth_sign requests. Added Ledger signature verification for eth_sign responses, matching the personal_sign pattern.
