Fix USDID registration key IDs and media-search response validation.
- Derive USDID key IDs from the saved public key and repair legacy random IDs without rotating the UUID or key pair.
- Raise
PrivateErrorfor missing, null or malformed media grids. Preserve valid empty results, skip malformed individual nodes, and stop repeated pagination cursors. - Live USDID registration passed in both SDKs. Live media-search validation confirmed the error contract; nonempty search availability was not demonstrated.
Thanks to @DazhongLee for the USDID fix and @v3ravani for the media-search fix.
