Add channel management features and localization support

- Implemented functionality to add new channels with a dialog interface. - Added validation for channel name and secret inputs, ensuring they meet specified criteria. - Integrated channel creation logic into the connection provider, including automatic slot assignment and MD5 hashing for channel secrets. - Updated localization files for multiple languages (Spanish, French, Croatian, Italian, German, Slovenian, and English) to include new channel-related strings. - Enhanced the contacts tab to display the add channel button conditionally based on device connection status. - Refactored the contacts tab to improve readability and maintainability.
