Support McpTransportContext in HttpServletSseServerTransportProvider #476
Description
Expected Behavior
#420 introduced McpTransportContext.
McpTransportContext should be supported in HttpServletSseServerTransportProvider to enable those who are still on that transport to leverage McpTransportContext to set attributes that Tools, etc. have access to. This is crucial for implementing Authentication & Authorization at the Tool level.
Current Behavior
McpTransportContext is absent from HttpServletSseServerTransportProvider
