Pull request overview

This PR migrates several gRPC-related HTTP filters (gRPC JSON transcoder, reverse transcoder, field extraction, and gRPC HTTP/1 bridges) from exception-based construction/validation to exception-free patterns using absl::Status / absl::StatusOr, aligning them with Envoy’s exception-free factory interfaces.

Changes:

• Convert filter factories to ExceptionFreeFactoryBase and return absl::StatusOr<Http::FilterFactoryCb>.
• Refactor filter/config constructors to report initialization failures via absl::Status& instead of throwing.
• Update affected unit tests to assert on returned absl::Status (via StatusHelpers::HasStatus) rather than exceptions.
