- FormatConnection now includes BackupConfigurationJson so a backup-only change
no longer renders identical Before/After cells (covers all 4 ConnectionsEqual fields)
- add ComputeConnectionsDiff(null, newConfig) first-deploy unit test
ComputeConnectionsDiff existed with tests but was never called and ConfigurationDiff
had no slot for it, so standalone connection endpoint/protocol/failover drift never
appeared in the deployment diff (only per-attribute binding drift did). Add a
ConnectionChanges slot, wire ComputeConnectionsDiff into ComputeDiff, and render the
connection section in the deployment diff UI.
