- Moved RNS initialization and logging setup to the main application to ensure proper logging capture before RNS is used. - Updated AnnounceService and PageFetcher to remove redundant RNS initialization, assuming it is handled in the main app. - Enhanced settings interface with a refresh button for better user experience and updated error and Reticulum log displays.
