feat: Refactor repeater resolution logic across multiple screens

- Implemented telemetry options for contacts, allowing users to enable or disable telemetry data sharing.
- Introduced a clear chat option in the chat interface for better message management.
- Updated the telemetry screen to handle telemetry data for contacts, including battery level.
- Refactored contact settings to include telemetry options and improved UI for better user experience.
