feat(localization): update contact settings translations for multiple languages

- Translated contact settings and related strings in Slovenian, Swedish, Ukrainian, Chinese, Dutch, Polish, Portuguese, Russian, and Slovak.
- Added new strings for discovered contacts actions such as adding, copying, and deleting contacts.
- Enhanced the DiscoveryContact model to include a rawPacket field for better data handling.
- Updated the contacts screen to support new actions in the context menu for discovered contacts.
- Improved the contact discovery store to handle the serialization of the new rawPacket field.
