Pull request overview

This PR migrates several HTTP filter factories and related helper code to Envoy’s exception-free factory pattern by switching to Common::ExceptionFreeFactoryBase and returning absl::StatusOr<FilterFactoryCb> / absl::Status on creation-time failures, and updates tests to validate status-based failures.

Changes:

• Convert multiple HTTP filter factories (set_metadata, set_filter_state, rbac, rate_limit_quota, proto_message_extraction) to exception-free creation (absl::StatusOr).
• Refactor RLQS global client/TLS store construction and proto message extraction config building to propagate failures via absl::Status instead of throwing.
• Update unit tests and Bazel deps to use StatusHelpers::HasStatus for error assertions.

File	Description
test/extensions/filters/http/rate_limit_quota/config_test.cc	Updates config tests for status-returning factory methods (also introduces a missing Bazel dep and still expects exceptions in one test).
test/extensions/filters/http/rate_limit_quota/client_test.cc	Updates client test to use creation-status out-parameter for exception-free construction.
test/extensions/filters/http/proto_message_extraction/filter_test.cc	Updates filter test to pass/verify creation status when building FilterConfig.
test/extensions/filters/http/proto_message_extraction/filter_config_test.cc	Converts exception-based assertions to status-based assertions and adds a helper for config creation (needs a small correctness tweak).
test/extensions/filters/http/proto_message_extraction/BUILD	Adds status_utility_lib dependency for new status assertions.
source/extensions/filters/http/set_metadata/config.h	Switches factory to ExceptionFreeFactoryBase and returns StatusOr.
source/extensions/filters/http/set_metadata/config.cc	Implements StatusOr factory creation for set_metadata.
source/extensions/filters/http/set_filter_state/config.h	Switches factory to ExceptionFreeFactoryBase and returns StatusOr.
source/extensions/filters/http/set_filter_state/config.cc	Implements StatusOr factory creation for set_filter_state.
source/extensions/filters/http/rbac/config.h	Switches RBAC HTTP factory to ExceptionFreeFactoryBase and returns StatusOr.
source/extensions/filters/http/rbac/config.cc	Updates signatures/returns for exception-free RBAC factory creation (still vulnerable to thrown exceptions from deeper construction).
source/extensions/filters/http/rate_limit_quota/global_client_impl.h	Converts global client creation helper to return StatusOr<unique_ptr<...>>.
source/extensions/filters/http/rate_limit_quota/global_client_impl.cc	Converts global client ctor failure paths from throwing to setting a status out-parameter.
source/extensions/filters/http/rate_limit_quota/filter_persistence.h	Updates TLS store getter to return StatusOr to propagate failures.
source/extensions/filters/http/rate_limit_quota/filter_persistence.cc	Propagates TLS/global client init failures via StatusOr.
source/extensions/filters/http/rate_limit_quota/config.h	Switches RLQ factory to ExceptionFreeFactoryBase and returns StatusOr.
source/extensions/filters/http/rate_limit_quota/config.cc	Propagates validation/TLS-store errors via status (but matcher construction can still throw).
source/extensions/filters/http/proto_message_extraction/filter_config.h	Updates FilterConfig to report creation failures via status out-parameter; converts init helpers to return absl::Status.
source/extensions/filters/http/proto_message_extraction/filter_config.cc	Implements status-returning initialization and converts multiple throws to status errors.
source/extensions/filters/http/proto_message_extraction/config.h	Switches factory to ExceptionFreeFactoryBase and returns StatusOr.
source/extensions/filters/http/proto_message_extraction/config.cc	Propagates filter config creation failures via status-returning factory methods.
