Enhance message decoder with additional port support

- Add support for decoding MAP_REPORT_APP, TRACEROUTE_APP, and NEIGHBORINFO_APP messages
- Create formatters for RouteDiscovery and NeighborInfo messages
- Remove JSON output from all formatters for cleaner display
- Update tests to check for proper formatting
