fix(mcp): bound MCP client requests with a session read timeout (#36675) 
An upstream that ends its response stream without a JSON-RPC reply leaves the
request pending forever. Tool discovery then only ended when an outer cancel
scope killed it, which logged a cancelled list_tools, ignored the timeout the
operator configured, and reported no tools to the client. Prompts and resources
had no outer guard at all.

Give the client session a read timeout so every request it sends is bounded,
including initialize. The SDK reports its own elapsed timeout as an McpError
carrying an HTTP status code in the field that otherwise holds JSON-RPC error
codes, and it relays an upstream's JSON-RPC error through that same class and
field, so the code alone cannot separate the two: an upstream answering with
application code 408 would be blamed on the gateway as a 504. Translate the
SDK's timeout into a TimeoutError in the module that configures the timeout,
matching on the elapsed timeout in the exception's context chain rather than on
the number, so the listing taxonomy never has to read a JSON-RPC code as an HTTP
status and every caller gets the same signal.

The bare cancellation warning is replaced by a line naming the server and the
budget that elapsed, and quiet_on_error does not demote it.
