* fix(bedrock): strip output_config from Bedrock Invoke requests
Bedrock Invoke API does not support the output_config parameter
(added to Anthropic Messages API). Requests with output_config cause
400 errors: 'extraneous key [output_config] is not permitted'.
Strip output_config in both Bedrock Invoke transformation layers
(messages and chat), consistent with how output_format is already
handled and how VertexAI strips both parameters.

* test(bedrock): add output_config test for chat/invoke path
Addresses review feedback — the chat/invoke_transformations path now has
symmetric test coverage matching the messages/invoke_transformations path.
