Improve settings XML handling by removing external dependencies

- Remove Apache Camel-K dependencies from settingsxml.go
- Add local Maven structs (Settings, Mirror, Server) with proper XML tags
- Fix URL trimming logic to handle multiple trailing slashes
- Add comprehensive test coverage with 11 test cases
- Clean up unused dependencies in go.mod

This change eliminates external dependencies while maintaining full functionality
for Maven settings.xml management and improves reliability.
