BedrockFilesConfig does not support file content retrieval

This is with the new LiteLLM Managed Files Configuration.

Line 993 (
bedrock_files_instance.file_content()
) is dead code — step 24 always short-circuits because
get_provider_files_config
returns non-None for bedrock. No config, header, or parameter can change this. It's a code bug.
