Sync from ADO internal review, fix example body param key

- Sync TypeSpec models from merged ADO PR (dirsMigrated, totalSkipped, RollingBack)
- Fix rebalanceJobs_Update example: body param key 'properties' (native TypeSpec)
- RebalanceJob is TypeSpec-native, no back-compatible.tsp entries needed
- Regenerated openapi.json and output examples
