Fix RNS initialization and logging setup

- 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.
