Summary by CodeRabbit

Improvements
- Firewall rule expansion now respects peer capabilities: detects native SSH and port-range support, prefers explicit ports over ranges, avoids redundant expansions, and conditionally appends native SSH access (port 22022) when supported and permitted.
Tests
- Added tests validating SSH-related port expansion across peer versions, protocols, single ports and ranges, dev-version variants, duplicates, and permission edge cases.
