- resolveIP now returns (string, error): error when result did not come
from the device's own SSH ping (service-side fallback or total
failure)
- migrateViaResolvConf and parseTargetURLAndResolveIP abort on error,
preventing a bad IP from being written to the device
- GetMigrationSummary captures the error in ResolveIPError and falls
back
to the hostname for the preview display; XML migration is unaffected
- Web UI shows a warning box with the error and a docs link when
resolution
is uncertain; migrate button stays enabled for the XML method
- Add hostname resolution troubleshooting section to TROUBLESHOOTING.md
