feat: add asset scanning unit tests for _asset_scan_status param and api_version header

[OMpawar-21]

Summary

• Add 9 unit tests to AssetsUnitTests covering the asset scanning feature
• Tests validate _asset_scan_status query param behavior on find(), fetch(), and upload()
• Tests validate api_version header behavior on publish()
• No changes to core SDK files — uses existing add_param() / add_header() from Parameter base class
