Integrate accurate previews into the SDKv2 bridge #2296
Description
This is a small reminder task to track integrating the work from:
- Disentangle deciding DiffResponse from detailedDiff #2293
- Implement schema-aware diffing for detail diff #2294
Into SDKV2 bridge and covering with some happy-path tests.
This should be flagged to enable rollout in the epic.
