Standardizes JSON output: depth, UTF-8, key order

- Sorts top-level config keys before serialization for deterministic files and cleaner diffs.
- Increases JSON depth to 10 to retain nested settings.
- Writes JSON as UTF-8 via Set-Content for consistent encoding.
- Applies across config export and UI save flows.
