wrapSSE only installed chunk-timeout monitoring when the response content-type included text/event-stream, so AWS Bedrock (application/vnd.amazon.eventstream) and other EventStream providers bypassed it entirely and chunkTimeout never fired.

Match text/event-stream and eventstream content types, and add an optional per-provider chunkTimeoutContentTypes list to include extra content-type substrings in the check.

Closes #26487
