Description
This PR backports the fix for serializing a TsFileResource whose in-memory TimeIndex has been degraded to FileTimeIndex.
When serializing a degraded resource and the .resource file still exists, TsFileResource now rebuilds a device time index through buildDeviceTimeIndex() for serialization instead of serializing FileTimeIndex directly.
It also adds coverage for region migration after TimeIndex degradation in an existing cluster IT class to avoid introducing another cluster restart path.
