Fold a List attribute's ElementDataType into the hashable projection so a
change to the element type (e.g. Int32 -> Double) with identical JSON-encoded
values is detected as a staleness/revision change. Inserted in alphabetical
position; null ElementDataType (scalars) is omitted by the canonical
serializer (WhenWritingNull), so scalar-only configs hash identically to
before. DiffService.AttributesEqual gains the same comparison to keep the
structured diff in parity with the staleness hash. Adds tests for differing
vs. equal ElementDataType (hash + diff) and the scalar no-op guard.
- 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.
