feat: add multi-host block support for SSH config management

- Support "Host server1 server2 server3" syntax in SSH configurations
- Add multi-host editing UI with separate host name inputs
- Implement multi-host block update and deletion operations
- Add comprehensive test coverage
- Maintain backward compatibility with single-host configs
