Fix incorrect JSON value used for tablet IDs in compaction status

The compaction status JSON builder mistakenly pushed the compaction name
Value into the tablet ID array instead of using the tablet ID itself.
This resulted in incorrect JSON output and could trigger RapidJSON
assertions when the moved Value was later reused as an object key.

Fix the logic by:
- Using tablet ID as the array element instead of the compaction name
- Ensuring each rapidjson::Value is used only for its intended purpose
- Cleaning up JSON construction to avoid reusing moved values
