feat(tui): show resource profile and CPU workload on cluster restore preview

- Displays current Resource Profile with parallelism settings
- Shows CPU Workload type (balanced/cpu-intensive/io-intensive)
- Shows Cluster Parallelism (number of concurrent database restores)

This helps users understand what performance settings will be used
before starting a cluster restore operation.
