Subject: [PATCH] Fix MCP Hub API tool call field name (#1842)

The Hub API expects 'name' field but the MCP server was sending 'tool'.
This caused all Hub-forwarded tools (list_l4_flows, get_l4_flow_summary,
list_api_calls, etc.) to fail with 'tool name is required' error.

Local tools like check_kubeshark_status were unaffected as they don't
call the Hub API.
