fix(mcp): expose client HTTP headers to logging callbacks and hooks (#36724)
* fix(mcp): expose client HTTP headers to logging callbacks and hooks

MCP protocol tool calls built a synthetic Request with only content-type, so metadata.headers reaching logging callbacks and guardrails was empty while /mcp-rest/tools/call exposed the full set. Rebuild the synthetic request from the connection's raw headers (shared with the sampling path), and pass sanitized headers to the pre-call hook, the MCP to LLM guardrail bridge and the Responses API MCP bridge. Credential headers stay masked and proxy key headers stripped.

* fix(mcp): drop custom proxy key header in the synthetic request builder

Strips general_settings.litellm_key_header_name in build_synthetic_mcp_request so every caller, including sampling, is covered, and reverts passing general_settings into add_litellm_data_to_request on the tool call path since that also switches on enforced_params.
