refactor: clean up verbose diagnostic logging from storage adapters

Remove verbose info logs from GCS and S3 storage adapters while keeping
critical warnings and error messages. This cleanup makes production logs
more actionable and less noisy.

Changes:
- Remove verbose cache check logging (structure details, field validation)
- Remove verbose GCS/S3 operation logs (download progress, parsing steps)
- Remove verbose pagination diagnostic logs (per-shard, per-file details)
- Keep critical warnings for invalid cache, null cache, recovery actions
- Keep error logs for actual failures
- Move successful operation details to trace level

Benefits:
- Production logs are now clean and actionable
- Critical issues still surface with warnings
- Debug details available via trace level when needed
- v3.37.8 cache validation remains fully functional

This completes the GCS persistence debugging journey (v3.35.0 → v3.38.0)
